Rays pitcher Alex Cobb will begin a rehab assignment Tuesday, according to the Tampa Bay Times. 

Cobb will pitch for the Class A Stone Crabs. He's expected to make at least two rehab starts at Class A. He'll likely be limited to four innings, or 60 pitches during his first start. Cobb had a 3.01 ERA in 83 2/3 innings prior to being hit in the head with a line drive. He has not pitched in the majors since June 15.
