Guard Kelly Oubre is joining the Golden State Warriors, giving the team backcourt depth in the wake of shooting guard Klay Thompson's latest injury.

Oubre was acquired Sunday in a trade from the Oklahoma City Thunder. The Warriors will send a conditional 2021 first-round draft pick and a 2021 second-round selection — via Denver — to Oklahoma City in the swap.

Thompson will miss the season after suffering a torn right Achilles' tendon playing a pickup game in Southern California on Wednesday. He already sat out the coronavirus-shortened season recovering from surgery for a torn ACL in his left knee that he hurt in the Raptors' clinching Game 6 victory of the 2019 NBA Finals.

"We've got to look hard and look fast," Warriors General Manager Bob Myers said Thursday when Golden State introduced No. 2 overall draft pick James Wiseman and second-rounder Nico Mannion at Chase Center. "But I've got some great guys I work with that are working right now on what we can do. And so we've got to fill that position."

Oubre. 24, is coming off a season in which he averaged career bests of 18.7 points and 6.4 rebounds over 56 games — 55 starts — for Phoenix. Oubre ended up with the Thunder on Monday night in the trade that sent Chris Paul to Phoenix.

The Warriors drafted Arizona guard Nico Mannion in the second round of the draft before knowing all the details of the injury to Thompson.

• The Suns, meanwhile, agreed on a three-year contract worth nearly $30 million with forward Jae Crowder, a big part of Miami's run last season to the NBA Finals.

In other moves:

•Utah gave Donovan Mitchell a max contract, a five-year extension that guarantees $163 million — starting with the 2021-22 season — and could be worth $196 million if he reaches the All-NBA level.

Mitchell averaged 24 points last season as a third-year player and first-time All-Star. He averaged 36.3 points in a seven-game series loss to Denver that included a 57-point game — the third-highest single-game total in NBA playoff history.

•Center Marc Gasol, who was drafted by the Lakers in 2007 but never played for them, accepted a two-year deal to join the team with which his brother, Pau, won two championships.

• Justin Holiday agreed to a deal to return to Indiana, meaning he and brother Aaron will be teammates again next season.

• Center Nerlens Noel, the No. 6 overall pick in 2013, agreed to a one-year, $5 million deal with the Knicks.

• Boston and Tristan Thompson agreed on a two-year, $19 million contract, ending his nine-year run with the Cavaliers.
