Boxberger could miss at least a month if his injury is indeed to his left oblique, Marc Topkin of the Tampa Bay Times reports.
Boxberger re-aggravated his surgically repaired abdomen Tuesday and was placed on the 15-day DL Wednesday. It's not yet known what the doctor's diagnosis is for his midsection but the Rays are saying that if it's an oblique strain, like they think, he will be out for at least a month.
