SEATTLE -- Chicago Cubs outfielder Ryan Sweeney will be placed on the disabled list after breaking a rib on his left side crashing into an outfield wall.
Chicago made the announcement Sunday, a day after he was hurt, and said Sweeney will be held out of baseball activities for four to six weeks.
Sweeney is hitting .295 with four home runs and 15 RBIs since he came up from Triple-A Iowa on May 6.
Chicago is off Monday and are expected to put Sweeney on the DL before Tuesday's game at Oakland.
Sweeney was injured in the third inning when he jumped and caught a fly ball by Kendrys Morales.
"It's unfortunate. We kind of started to seem to get things going a little bit with the offense, and now we lose a big piece of that," Cubs manager Dale Sveum said. "It's unfortunate for him, too. He's trying to get his career going and getting a chance to play every day. It stinks when those things happen to guys like that who are really good players and getting a chance, and all of a sudden it's taken away for a couple of months."
