Patterson was chasing down a loose ball at the end of the first quarter when his leg collided with Outlaw's knee. He was helped off the floor by trainers.
Both Patterson and Outlaw suffered left knee contusions, according to Jonathan Santiago. Outlaw was able to return, but Patterson's status is listed as "questionable."
Patterson came off the bench and played just three-and-a-half minutes before suffering the injury. He missed his only shot, a three-point attempt, in his time on the floor.
Through seven games, he is averaging a career-low six points, while his field goal and three-point shooting percentages are both career worsts.
A contusion is probably the "best" injury that could have come out of the collision. At first glance, it looked like it could have been an ACL injury, which would have been awful news.
A contusion may sideline Patterson for a few games, but it shouldn't be too serious.
