Bobby Simmons can't pinpoint when it happened during the Milwaukee Bucks' home-court victory over the Cleveland Cavaliers on Dec. 10.

But during that game, Simmons bruised his right shoulder, an injury that has kept him out of the lineup for the last four games.

The 6-foot-6 forward was able to take part in practice Monday at the Cousins Center, giving him hope he can return to the lineup when Milwaukee meets the defending champion San Antonio Spurs tonight at the Bradley Center.

"We'll have to see how it feels tomorrow and go from there," Simmons said. "It felt pretty good, just getting back on the floor and getting up and down, once I got my energy going a little bit. It's just a matter of what I can withstand."
