Howland said he was hopeful that Collison would return in time to play against George Washington November 28th.
The decision to keep Collison in civilians was made after Howland watched Collison work out in Pauley Pavilion Wednesday evening.
"Unfortunately, his knee isn't as healthy as we would like it to be," Howland said Thursday morning.
"He was moving pretty good (Wednesday night) but he was wearing a brace on the knee and he is not as explosive yet as you would want him to be yet. We want him to be as effective as possible so it was my feeling to air on the side of caution. He saw the doctor (after the workout) and the doctor concurred that he should be out at least 10 more days. So, probably, the earliest he could be back would be the 28th (of this month), for George Washington."
Collison, then, would miss the CBE Classic semi-final against Maryland on Monday, and the potential final on Tuesday. Howland also expected him to miss the home game against Yale on November 223rd.
Collison suffered a knee sprain November 2nd in UCLA's exhibition game agaisnt Azusa Pacific. He hasn't played in a game since and only recently started going through individual drills.
