3/16 Injury updates

* 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 everyday,” Jackson said Saturday in Mesa. “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.”

He 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.

* 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. Stewart did play Thursday, his first game action since Feb. 21.

* Matt Garza is making progress with his throwing program. So far, no time table for him to get on a mound.
