Chicago ? Kerry Wood will have a bone scan Monday after he cut short a live batting practice session Sunday when he felt more discomfort in his right triceps.

The Chicago Cubs right-hander was put on the disabled list Thursday, retroactive to May 12, and hoped to come off this Thursday and pitch Friday in Pittsburgh.

He left a start against the Dodgers on May 11 after two innings because of soreness in the triceps and has missed two starts since.

Wood warmed up in the bullpen Sunday and then went to the regular mound at Wrigley Field. But the batting practice session against real hitters lasted just eight pitches before Wood walked off the mound and into the dugout.

“He’s not in any severe pain. We optimistically feel it’s what we felt it was the other day. But since he didn’t feel any better today and had a little discomfort, we’re going to get the last test tomorrow and go from there,” general manager Jim Hendry said.

“We’re not anticipating anything negative.”

The decision to have the bone scan was made after Hendry discussed the situation with Dr. Stephen Gryzlo, the team’s orthopaedist.

Earlier tests, including an MRI, showed inflammation in Wood’s triceps, but no tears.

Hendry said he had no idea if Wood still would be able to pitch Friday in Pittsburgh, despite Sunday’s obvious setback.
