Golden State Warriors guard Klay Thompson suffered a leg injury during a workout in Southern California on Wednesday, the team announced.

Chris Haynes of Yahoo Sports reports the Warriors fear it is a "significant Achilles injury." An MRI is scheduled for Thursday morning.

The team announced the injury without providing further details about the severity or any timeline for his availability with training camp starting Dec. 1 and the season beginning Dec. 22. Thompson was scheduled to be evaluated in the coming days, Golden State said.

It was unclear how this might affect Golden State's draft decisions Wednesday, when the Warriors held the No. 2 overall selection. They eventually took Memphis Tigers centre James Wiseman, who played just three NCAA regular season games.

This could be a severe blow for the Warriors, who finished with the worst record in the NBA last season. Thompson didn't play at all during the coronavirus-shortened season as he worked back from surgery for a torn ACL in his left knee. He suffered that injury in the deciding Game 6 of the 2019 NBA Finals against the Toronto Raptors.
