Jackson dealing with inflamed right shoulder

Jackson dealing with inflamed right shoulder

LAS VEGAS -- Cubs outfielder Brett Jackson had an MRI on his right shoulder, which revealed some inflammation. He'll be sidelined about one week.

"I'm going to keep working every day," Jackson said on Saturday in Mesa, Ariz. "No. 1 is to get 100 percent healthy again. I'm confident that we're going to take care of that quickly, and obviously when I'm back we'll focus on what's next."

Jackson said he felt the soreness throwing.

"I'm confident we're going to knock it out quickly and be healthy for the season," he said.

• Third baseman Ian Stewart, trying to come back from a sore left quad, chose not to play in a Minor League game on Saturday and instead continue to rehab his leg. The Cubs are letting the third baseman tell them what he can and can't do. Stewart did play on Thursday in a Minor League contest, his first game action since Feb. 21, when he injured his leg.

• Matt Garza, sidelined with a strained left lat, is making progress with his throwing program. So far, there is no time table for him to get on a mound. Garza was not expected to be ready for the regular season until May at the earliest.
