Cleveland Cavaliers rookie point guard Kyrie Irving will miss at least the next two games as he continues to recover from a concussion.

Head coach Byron Scott said Irving is getting better, but will be held out of games Friday against Milwaukee and Saturday against Philadelphia.

"We're still going through the NBA protocol, but he'll be out tonight and tomorrow," Scott said Friday. "We'll just go from there. He's making improvements, but we're not going to risk putting him out there until the doctors say he's fine."

After this weekend's action, the Cavs don't play again until Wednesday against Indiana. He already missed one game because of the injury, sitting out this past Wednesday's contest against the Clippers.

Irving suffered the concussion after being kneed in the head during the fourth quarter of Tuesday's loss to the Miami Heat. He experienced headaches after the game that worsened over the course of the night and during pregame activities prior to Wednesday's contest.

"We all know how serious this thing can be," Scott added. "That's why we are taking such a cautious look at this. We don't want to put a young man at risk. That's the biggest thing. The NBA has done a terrific job as far as trying to diagnose and figure out what to do with concussions."

In 23 games this season, Irving has averages of 18.0 points, 5.1 assists and 3.5 rebounds.

The Cavaliers signed guard Ben Uzoh to a 10-day contract on Friday to add backcourt depth.
