Blackburn (wrist) will miss longer than the minimum 10 days with his injury, Alex Simon of MLB.com reports. "Right now, he hasn't gotten to the point where he's able to play catch or really even grip a baseball," Athletics manager Bob Melvin said. "It may take a little longer than we originally anticipated."
The rookie has been dealing with swelling in his injured right hand, as well as limited range of motion. While he's eligible to return Sept. 2, Blackburn's lack of progress has rendered that date irrelevant. With more testing on tap in the coming days, Blackburn may not be able to return until close to mid-September, which would potentially afford him two or three more starts before the end of the season.
