KANSAS CITY -- Instead of attending the Royals Welcome Home Luncheon on Tuesday, closer Octavio Dotel was getting an MRI of his sore left oblique, which has kept him off the mound since Thursday.
"It's just to give us some idea of if it's any more serious than we think it is," Royals manager Buddy Bell said on Tuesday.
Bell said Dotel would throw on Wednesday, but he would not be available to pitch in the game that night against the Red Sox.
"We'll see how he feels," Bell said. "If he can't pitch on Thursday, more than likely, we'll put him on the disabled list. We'll wait until [Wednesday] to make a more solid decision on that."
In Dotel's absence, Bell said he would use David Riske, who was signed to be the primary setup man, in the closer role.
Dotel was not the Royals' only concern on Wednesday. Starter Odalis Perez left two of his final three Spring Training starts after three innings because of a blister on his left middle finger.
"We've still got a little bit of an issue with his blister," Bell said. "The last time he threw it was fine [when he started], and [then] he had some problems. Our bullpen is well rested, so we'll have some insurance. We wouldn't pitch him if we thought it was going to be an issue, but if it does, we do have some insurance."
Perez said on Tuesday that he's had a finger blister "only two times in my entire career."
"I don't think there's any concern," he said.
