UMass guard Trey Davis was hurt after running into a screen set by a Dayton player on Thursday night.
According to Yahoo Sports, Davis writhed on the ground for "several minutes" after the collision.
After the game, Minutemen coach Derrick Kellogg told reporters Davis said he was "OK," but that the team would see how he is for Saturday's game at St. Louis.
UMass won Thursday's game over Dayton, 66-64.
