A day after pulling out a gutsy marquee victory, No. 15 Iowa State could be without its leader on Tuesday when the Cyclones face Creighton in the second day of the Players Era men's championship in Las Vegas.

Iowa State (5-0) rallied late for an 83-82 victory over No. 14 St. John's on Monday, but senior guard Tamin Lipsey exited in the final minutes with a lower-body injury. Lipsey, a preseason All-Big 12 honoree, scored 16 points before limping off the court in pain.

"In regards to Tamin, we're still evaluating it," Iowa State coach T.J. Otzelberger said postgame. "The training staff, medical staff, told us it's going to be day-to-day with a lower-body injury. I don't have great detail on it. We'll get back to the hotel, check him out and see what that means."
