"He's had bad luck, no doubt," manager John Gibbons said. "I don't think it's a major thing, but you know, we can't be sure."
The 30-year-old Reimold has dealt with multiple injuries over his career, and he has had surgeries on his neck and Achilles tendon. He has played just 60 Major League games since the beginning of 2012.
Toronto claimed Reimold off waivers from Baltimore on Sunday, and Reimold has played in four games for the Blue Jays.
Gose, who flew into St. Petersburg at 6:45 a.m. ET on Saturday, started Saturday's game in right field in Reimold's place.
"I mean, any time you're up here, it's good," Gose said. "They kind of informed me last night that there was a chance, then woke up bright and early this morning."
The 23-year-old Gose is batting .229 in 44 games for the Blue Jays this season.
"Just flip him out for Reimold, basically," Gibbons said. "We can go either way out there, with him and [Colby] Rasmus and [Darin] Mastroianni."
Toronto could have returned Jose Bautista to right field -- he hasn't played the position since June 22 while recovering from a nagging hamstring injury, but he is healthy enough to do so -- but elected to keep Bautista at first base and play Gose in right.
Gibbons said he could put Bautista back in right field on Sunday to avoid a tough matchup for the left-handed Gose against Tampa Bay's David Price, if Price -- who is dealing with an illness -- is able to make his start.
"Depending on who pitches tomorrow, if it's a lefty, Bautista might be playing right tomorrow," Gibbons said.
