Timberwolves coach Rick Adelman knew there would be nights like after the team brought Brandon Roy out of a one-year retirement.

Roy did not play in the second half of Friday's victory over Indiana because of a sore right knee, and the shooting guard sat out Saturday's game in Chicago for the same reason.

Adelman said he isn't worried this will be long-term. On the other hand, when dealing with anyone with a history of knee problems -- which forced Roy's retirement -- Adelman said he expected there would be nights when Roy would not be available.

"Anybody who has had knee problems, you're going to have things where you step back a little bit," Adelman said. "So I'm not going to be overly concerned right now. I think we just have to take it day by day and go from there."

That means there is no guarantee Roy will be ready to play Monday in Dallas. And that means the Wolves will likely be even more shorthanded against the Mavericks, considering the left knee injury suffered by Chase Budinger on Saturday. By the time the game was over, the Wolves were down to just Alexey Shved at shooting guard.

Roy has struggled to return to the form he had earlier in his career with Portland. He has averaged 5.8 points per game and is shooting 31.4 percent from the floor. Again, Adelman said, it's a process.
