Chicago Cubs reliever Joe Borowski will miss at least six weeks with a broken bone in his arm, another loss for a pitching staff already with injuries to Kerry Wood and Mark Prior.
Borowski sustained a non-displaced fracture in his right ulna when he was hit by a line drive in Monday's 12-5 loss to Kansas City.

He is wearing a splint and will begin a throwing program when the healing process is complete, approximately six weeks.
Borowski was attempting to come back from a partially torn rotator cuff in his right shoulder this spring. The injury ended his season in June last year.
"I've worked so hard to get back, and I'm just going to take this as another bump in the road," Borowski said. "Fortunately, all the doctors say it should heal without any problems. That's good news."
In 2003, Borowski saved 33 games for the Cubs and he appeared to be on the way to regaining his job as closer this spring.
The injury means the Cubs will have to scramble again to fill a hole on their pitching staff. They're already without their top two starters, Wood and Prior. Wood has bursitis in his shoulder, and Prior has inflammation in his elbow.
