Hernandez (oblique) will have an MRI on Tuesday or Wednesday, as the injury is more serious than originally thought, Bill Koch of The Providence Journal reports.

EDGE Analysis

The team initially thought Hernandez would be able to return soon from the injured list, but he is in more pain now, so they will run some tests. Pitchers can end up missing significant time with serious oblique strains, so he should be considered out indefinitely for now.
