Prior to today's Phillies-Astros series finale, Jimmy Rollins underwent an MRI on his injured left ankle.

The team said the measure was "to make sure it's healing" the way it should be. They continue to say the shortstop has been progressing fine; but in the last two nights, Rollins has hobbled down to first base in pinch hit attempts.

The defending National League MVP has been out of the starting lineup since injuring the ankle April 8. If the MRI results don't turn out as the Phillies expected and he needs to go on the disabled list, Rollins wouldn't be eligible to come back until Thursday, May 1 against San Diego.

UPDATE: Phillies assistant GM Ruben Amaro said Rollins' MRI checked out fine. The team expects Rollins to make an attempt to get back on the field Saturday or Sunday.
