Rays starter Alex Cobb will not throw a bullpen session Sunday, according to the Tampa Bay Times.
Cobb was pulled from Tuesday's rehab start after just two pitches with a blister issue. He was expected to throw again Sunday, but that has been pushed back at least a day. It's been reported that Cobb will need three to four starts before he's ready to return.
Cobb has a 3.01 ERA in 83 2/3 innings.
