DUNEDIN, Fla. -- Right-hander Sergio Santos is expected to be out of action until Saturday because of a sore right triceps muscle.
Santos left Sunday's game versus the Phillies with discomfort in the area. He was originally expected to pitch Thursday versus Baltimore, but will now be held out for an additional couple of days.
"Nothing yet that we're too alarmed about, because there's still so much spring left," manager John Gibbons told media members on Tuesday afternoon.
Santos' injury might be considered minor, but if it lingers the Blue Jays could find themselves with a rather problematic situation on their hands. Closer Casey Janssen recently made his return to the mound following offseason shoulder surgery, but has yet to face live hitters.
Outfielder Colby Rasmus' return to Toronto's lineup also will take a little bit longer than originally expected. Rasmus was supposed to play on Tuesday against the Orioles, but has now been ruled out until Thursday.
The 26-year-old is dealing with a sore right shoulder, but the injury is still considered relatively minor. Rasmus was sent for an examination last week and structural damage was ruled out at that time although he is dealing with inflammation in the area.
Rasmus, who has appeared in three games this spring, is set for another year as Toronto's everyday center fielder. Last season, he hit .223 with 23 homers and 75 RBIs in 151 games.
