The good news is that neither should miss too much time. Toronto manager John Farrell said before Saturday's game that both players are day to day, and it doesn't seem like they'll have to head to the disabled list.
Rasmus, especially, has a good prognosis. He strained his groin while running in to catch Derek Norris' fly ball in the bottom of the 11th inning on Friday, but stayed in the game and hit a double in the 12th before Farrell pulled him as a precaution.
The outfielder believes that he could return on Sunday. Though Farrell was less optimistic, he, too, left open that possibility.
"I don't want to say it's nothing, but to me it's nothing serious," Rasmus said. "Just hopefully, like I said, be back in there [on Sunday]. So it's no big deal, just came out just to make sure [not to injure it further]."
Lawrie may be out a bit longer. The pain he felt in his ribcage actually dates to the Blue Jays' series against the Yankees in mid-July. He played through it initially, but when Lawrie aggravated the injury in his at-bat leading off Friday's game, he had to sit.
"He is tough," Farrell said. "He's got a high pain threshold, but I think it got to the point where he had to say, 'You know what, I've got to protect against this.'"
Farrell said Lawrie would be re-evaluated on Tuesday after the team's off-day on Monday.
