Putkonen may be called upon immediately, as manager Jim Leyland announced that reliever Brayan Villarreal wouldn't be available on Tuesday after pitching three combined innings on Saturday and Sunday.
"Villareal's off today. He will not pitch today. Tell all the fans, all the talk shows, everybody," Leyland said. "He's getting two full days off. He deserves it. I've got to be careful with him, because he's got that violent delivery."
The Tigers recalled Putkonen from Triple-A Toledo, where the right-hander was 2-2 with a 3.32 ERA in 19 innings this season. Dotel, who hasn't pitched since June 2, is on the DL retroactive to June 3.
"It's one of those deals we've been fighting through all year," Leyland said. "If [Dotel's] not ready to pitch Tuesday, that means he's probably not ready to pitch Wednesday. It's only going to be about a five-day thing, so why not do it? We can't keep going short all the time, particularly in the National League."
