After undergoing arthroscopic knee surgery yesterday, Brandon Roy will now be sidelined on the Minnesota Timberwolves bench for at least a month.

The Wolves offered no other details about an exploratory operation intended to clean up his right knee and perhaps give him peace of mind.

Rick Adelman didn't sound certain if this was just a pause in Roy's comeback or if it's something much more.

"From the very start you knew it was going to be up and down," he said before today's surgery. "It's too bad it's this. But I think he feels like this is worth doing, making sure everything's all right. You just have to go with it and hopefully when it's over with, he'll be able to come back."

So far Roy has played five games with Minnesota, averaging 5.8 points, 4.6 assists and 2.8 rebounds while shooting 31.4 percent from the field in 24.4 minutes a game.

In the team's final preseason game on Oct. 26 against the Milwaukee Bucks, Roy banged his right knee that later formed a bump and bruise. He later aggravated the same knee on Nov.9  in the first half of a game against the Indiana Pacers.
