Darren Collison will miss at least two more games for No. 2 UCLA while the preseason All-American guard recovers from a sprained left knee.

The Bruins host Youngstown State on Monday night in a first-round game of the CBE Classic. They'll play another game Tuesday night, with the top team in the West region advancing to the semifinals Nov. 19 in Kansas City. Also in the bracket are Weber State and Cal State-San Bernardino.

Collison will run on a treadmill Monday. If a doctor gives him the go-ahead, the junior could do some floor workouts and possibly begin practicing Thursday, coach Ben Howland said.

"He's doing better. He will be out for sure on Monday and Tuesday," the coach said.
