Cobb threw the simulated game on Monday at Tampa Bay's spring training complex in Port Charlotte, Florida. Cobb threw four innings with 15 pitches per inning. Cobb has been out since April 13 and became the third Rays starter to land on the disabled list joining Matt Moore and Jeremy Hellickson.
Tampa Bay manager Joe Maddon said the club needed to see how Cobb responds the day after throwing, but he could appear in a game this weekend. Maddon also said it's possible Cobb might only need one rehab start before rejoining the club.
Cobb was 1-1 with a 1.89 ERA in three starts before going on the disabled list.
