Swisher was held out of New York's lineup on Thursday after exiting the previous game with tightness in his biceps, which he felt after a seventh-inning swing.
"It's just a little tug, kind of like how you stretch out a rubber band," Swisher said. "You just feel something kind of sharp."
Swisher said that he has been working with assistant athletic trainer Steve Donohue, and he planned to spend most of his remaining time in Detroit around the training room.
"I feel good today," Swisher said. "Me and Stevie D., we're 'road dogs.' We're going to hang all day together."
Yankees manager Joe Girardi was not sure if Swisher would be available as a pinch-hitter on Thursday, but the outfielder said that he could be.
"If skip needs me today, I'd do everything I could to get out there and play," Swisher said.
