"His shoulder's a little tender," Toronto manager John Gibbons said after the Jays' 5-4 win over the Baltimore Orioles. "I don't think it's a big deal but no use pushing it right now."
Cecil, a left-hander, is in contention for the Jays' closer role. Right-hander Aaron Sanchez served as closer at the end of last season but is currently bidding to join the starting rotation.
Cecil, whose arrival at spring training was delayed by a bout of the flu, pitched in Monday's intra-squad game.
