Jennings, who was injured during Saturday night's loss to the Bucks, underwent surgery to repair the injury. No timetable is being placed on the guard's return at this time, the team announced.
Jennings took to Twitter early Wednesday morning, saying that the surgery was successful.
Successful Surgery. Thanks for the love & support. I appreciate it! pic.twitter.com/Ir1xKrjR98— BRANDON JENNINGS (@BrandonJennings) January 27, 2015
Jennings fell to the floor after planting on his left leg while guarding an inbounds pass Saturday. He immediately clutched the leg above his sneaker while writhing on the floor in pain.
The 6-foot-1 guard has appeared in 41 games this season, averaging 15.4 points, 6.6 assists and 1.1 steals in 28.6 minutes per game.
Coming into Sunday, Detroit had won 12 of 16 to climb back into the Eastern Conference playoff race after a terrible start. But it will be difficult to maintain that pace without the 25-year-old Jennings.
The Pistons lost to the Raptors 114-110 on Sunday night in their first game since Jennings' injury.
Detroit has not reached the postseason since 2009. It's the longest active drought in the East.
Coach Stan Van Gundy said he feels bad for Jennings, who loves playing "probably as much as anybody I've been around.''
"He plays all summer, he loves being in the gym,'' Van Gundy said. "On top of that, he was having the best season of his career, particularly lately, so it's really tough. It's tough for us but it's even tougher for him, and I feel real bad for him because he was playing so well and then to have it end when he was on such a run is really unfortunate.''
Augustin scored a career-high 35 points in Sunday night's loss.
