Minnesota Timberwolves' Karl-Anthony Towns (wrist) upgraded to questionable vs. San Antonio Spurs

Minnesota Timberwolves center Karl-Anthony Towns -- who has missed six games because of a left wrist injury -- is expected to be a game-time decision Saturday against the San Antonio Spurs, sources told ESPN.

The Timberwolves upgraded Towns' status to questionable on Friday. He has been working out with the team this week and has been eager to return as soon as possible.

Towns suffered the injury after landing on his left hand in a Dec. 27 win over the Utah Jazz. The star big man had season-ending surgery on his left wrist a year ago, but this injury was in a different spot, sources said.

Towns, 25, is averaging 19 points, 11.5 rebounds and 5 assists across the two games he has played this season.
