Anthony Gose has been recalled from triple-A Buffalo.
Toronto claimed Reimold off waivers on July 6. He has played in just 56 major-league games since 2012 after a second spine-fusion operation.
Reimold had a .333 batting average in four games with the Blue Jays.
Gose has a .229 average in 44 games with Toronto this season including five runs batted in and five stolen bases.
Reimold was hurt running the bases in the fourth inning of Friday night's game with the Rays.
Toronto manager John Gibbons doesn't think Reimold's injury is a major one.
