The 6-foot-8 forward hurt the shoulder during last week's 68-51 loss at Illinois. He was in uniform Sunday but did not play in the 65-62 home loss to Michigan.
Coach Ed DeChellis said Monday that Brooks was working out and doing light basketball drills, though he might not be a full go at practice until trainers were satisfied with the level of strength in the shoulder.
DeChellis said the timeline could be between three and seven days. The next game for Penn State (12-10, 5-6) is Thursday at Michigan State (13-10, 5-6).
Brooks averages 7.2 rebounds. He's also Penn State's second-leading scorer (13.2 points) and best interior defender.
