OF Jackson (shoulder) sidelined a week

MESA, Ariz. – An MRI on Chicago Cubs outfield prospect Brett Jackson indicated he has inflammation in his right shoulder which will sideline him for a “week or so.”

“Just came up from throwing,” Jackson said Saturday morning. “One of those spring training things.”

Jackson was having a good spring but was experiencing shoulder “soreness” off and on for about a week. He was a late scratch from a game on Friday.

“No. 1 is getting 100 percent healthy again,” he said. “I’m confident that we’re going to take care of that quickly. When I’m back we’ll focus on what’s next.”

Jackson is slated to open the season at Triple-A Iowa after appearing in 44 games for the Cubs last season. He’s hitting .313 with four runs batted in this spring after re-working his swing in the offseason.

Third baseman Ian Stewart is still suffering from soreness in his left quad and will play in a minor league game on Sunday instead of Saturday as first announced. He’s been out since early in spring training when he injured himself running the bases in an intra-squad game. He played in a minor league game on Thursday but took Friday and now Saturday off.
