The U.S. men's 3x3 basketball team's tough start to the Paris Olympics got even tougher on Thursday, as former BYU star Jimmer Fredette sat out Team USA's loss against Lithuania.

Fredette first suffered the injury in Wednesday's loss to Poland, noticeably compromised after requiring medical attention to his groin area. 

Fredette was still moving gingerly during team warmups on Thursday and did not appear in game action, instead serving as a coach throughout (coaches aren't allowed courtside in 3x3, requiring players to fill the role themselves).

The exact nature and severity of the injury are still unclear, and it remains to be seen whether Fredette will try to play in the U.S.'s second game on Thursday against reigning gold medalists Latvia.

Team USA battled without Fredette in the lineup, but Lithuania pulled away in the final minute to hand the Americans their third straight loss to start Olympic competition. It's been a tough couple of days for a team that was expected to contend for a medal after taking home silver at last year's FIBA World Cup. And it's hard to imagine them digging out of this hole without Fredette.
