A legend in the sport of volleyball is stepping down, as longtime Nebraska head coach John Cook announced his retirement on Wednesday.

Joining Nebraska in 2000 after seven years with Wisconsin, Cook's 25 years at the Cornhuskers' helm included 14 conference titles, 12 trips to the NCAA Final Four, and four national championships (2000, 2006, 2015, 2017). Most recently, Cook led the team to back-to-back national semifinal appearances.

Even more, Cook turned Nebraska volleyball into a can't-miss phenomenon. The Huskers are currently riding a 339 home match sellout streak dating back to 2001 — an NCAA record for all women's sports.

The three-time AVCA National Coach of the Year (2000, 2005, and 2023) also helped Nebraska stage two volleyball matches in their football stadium in August 2023, when 92,003 fans packed Memorial Stadium to break the international women's sports attendance record.

Cook retires with an overall 883-176 career record — the fifth-best all-time winning percentage in Division I (DI) volleyball history. His 722-103 resume with Nebraska makes him the winningest DI coach in the sport this century.

"I’ve been here for 25 years. That’s a long time to do something. It’s been a great run," Cook said in the school's announcement.

"For me personally, the greatest accomplishment in coaching is seeing former players...taking the lessons they’ve learned from being a Nebraska volleyball player and applying it to their everyday lives," he continued. "There is no greater reward in coaching than that."

"I’ve always said to 'Dream Big,' and we’ve dreamed bigger than any volleyball program in the history of the world."

Alumna Dani Busboom Kelly succeeds Cook

Cook's successor is former Nebraska volleyball star Dani Busboom Kelly, who helped earn the 2006 national title as the starting libero before serving as Cook's assistant during the Cornhuskers' fourth title run in 2015.

Busboom Kelly took over as Louisville's head coach in 2017, leading the Cardinals to the program's first-ever Final Four in 2021 and following it up with national championship game appearances in 2022 and 2024. She exits the ACC squad with a 203-44 record and has agreed to a six-year contract with her alma mater.

"The opportunity to come home to Nebraska is more than a dream come true," Busboom Kelly said in a statement. "Nebraska is the greatest place in the world to play volleyball and I am honored to be a part of it once again!"

Two key upsets headlined Thursday's WNBA bill, sending the Phoenix Mercury soaring into third place in the league standings while the No. 6 Golden State Valkyries continued to outwit opponents.

The red-hot Mercury snagged their fourth straight win by taking down the No. 2 New York Liberty 89-81 on Thursday night, overcoming an 35-point performance from two-time MVP Breanna Stewart with five double-digit Phoenix scorers.

Meanwhile out West, the Valkyries stifled a surging No. 7 Fever, downing Indiana 88-77 in part by holding star guard Caitlin Clark to just 3-for-14 from the field — and 0-for-7 from behind the arc.

"We were being disruptive, we know that she doesn't like physicality, we know that she wants to get to that left step-back," Golden State head coach Natalie Nakase said about the Valkyries' strategy to effectively contain Clark.

Though the No. 1 Minnesota Lynx and 2024 WNBA champions New York still hold court atop the table, Thursday's actions proves that other squads are making some unexpected in-roads.

Putting together an impressive road record are the Mercury, who will ride a 4-2 away record into their Saturday matchup against the No. 11 Chicago Sky — the last stop on a four-game road trip that's been perfect for Phoenix thus far.

Already flipping the script on expectations is Golden State, with the 2025 expansion team rising despite relying on a hodgepodge roster as several players compete at EuroBasket 2025. The Valkyries will aim to keep their winning momentum in their Sunday clash with the No. 12 Connecticut Sun.

How to watch the Mercury, Valkyries this weekend

Both of Thursday's victors will be back in action this weekend, with Phoenix facing Chicago at 1 PM ET on Saturday, airing live on ABC.

Then on Sunday, Golden State will host Connecticut at 8:30 PM ET, with live coverage on WNBA League Pass.

In another weekend full of WNBA action, all eyes are on Las Vegas, as the No. 8 Aces will try to curb a two-game losing streak against two formidable opponents.

A successful weekend for Las Vegas could hinge on three-time WNBA MVP A'ja Wilson's potential return from injury, with the star forward recently upgraded to "questionable" after landing in concussion protocol last week.

Overall, the margin for error has narrowed in the middle of the WNBA pack, as talented teams continue to translate quality performances into consistency.

• No. 5 Seattle Storm vs. No. 8 Las Vegas Aces, Friday at 10 PM ET (ION): The Aces will try to end their free fall in Friday's head-to-head battle with a Seattle side that can beat anybody at their best.

• No. 7 Indiana Fever vs. No. 8 Las Vegas Aces, Sunday at 3 PM ET (ESPN): Las Vegas next faces a Fever team still smarting from Thursday's away loss to the Golden State Valkyries, with both teams narrowly clinging to positions above the playoff line.

• No. 2 New York Liberty vs. No. 5 Seattle Storm, Sunday at 7 PM ET (WNBA League Pass): The Liberty have a comfortable hold on second place, but with two losses in their last three games, New York is flirting with danger entering their Sunday game with Seattle — particularly if star big Jonquel Jones is out after suffering a knock to the ankle on Thursday.

Ultimately, there's no rest for the weary in the WNBA, as a series of difficult matchups can see a single error quickly slide into a losing streak.

The final NWSL weekend heading into the league's six-week summer break has arrived, giving teams one more chance to prove themselves before regular-season play pauses to make way for major international tournaments.

With a five-point gap separating No. 1 Kansas City from No. 2 Orlando in the NWSL standings, the Current will enter the break as the 2025 Shield frontrunners regardless of this weekend's results.

Despite Kansas City's grip atop the table, there's still plenty of room for movement both above and below the postseason cutoff line, as clubs across the NWSL look to wrap their midseason finales on a high note:

• No. 1 Kansas City Current vs. No. 10 Angel City FC, Friday at 8 PM ET (Prime): Angel City has a shot at launching themselves above the cutoff line on Friday, but they'll have to snap the Current's five-game winning streak to make it happen.

• No. 8 Gotham FC vs. No. 9 Bay FC, Saturday at 7:30 PM ET (ION): Gotham and Bay FC enter the weekend tied on points while staring at each other from on opposite sides of the playoff line — meaning a Saturday win for either club could set the tone for the rest of the 2025 season.

• No. 3 San Diego Wave FC vs. No. 4 Washington Spirit, Sunday at 10 PM ET (CBS Sports): The weekend's only top-table clash could see San Diego sprint back into second place — unless Washington leapfrogs the upstart Wave to claim the third-place spot.

The LPGA Tour has turned its attention to Texas, with the 2025 KPMG Women's PGA Championship — the third major of the pro golf season — teeing off in Frisco to a flurry of first-round action on Thursday.

All of the sport's Top 100 athletes are participating in this week's event, including No. 1 Nelly Korda, who sits in a 14th-place tie with an even-par first-round performance, and surging US dark horse No. 50 Lexi Thompson, who tied for 10th in her Thursday return from a brief retirement.

However, leading the pack heading into Friday's second round is Thailand's world No. 2 Jeeno Thitikul, who finished the first day of competition atop the leaderboard with a score of 4-under-par.

Australia's No. 24 Minjee Lee also posted a strong start, capping Thursday at 3-under to sit in second place.

While the sport's best chase victory on the links, the 2025 KPMG Women's PGA Championship is already making history off the green.

Not only is it the first-ever women's major to tee off at Frisco's Fields Ranch East, the tournament also increased its purse to $12 million on Tuesday — nearly tripling the $4.5 million prize pool from just four years ago and tying the US Women's Open for the LPGA Tour's highest payout in the process.

The third LPGA Grand Slam of 2025 continues through Sunday.

Friday's second round will air live on the Golf Channel, while coverage of Saturday and Sunday's final rounds will air across NBC and Peacock.
