Twins manager Ron Gardenhire said there's a chance Doumit could pinch-hit in case of emergency, but that his thumb has been bothering him for about a week after jamming it swinging.
"He thinks he could probably hit right-handed in a pinch, but he can't catch," Gardenhire said. "His thumb is better than it was yesterday. It was really ugly."
If Doumit doesn't see any action against the Blue Jays, he'll finish the year with a .275 batting average with a career-high 18 homers and 75 RBIs in 134 games.
