The Blue Jays transferred Mantipky (knee) to the 60-day injured list Wednesday, Ben Nicholson-Smith of Sportsnet.ca reports.
Mantiply is set to undergo arthroscopic surgery on his left knee, so the Blue Jays will stash him away on the 60-day IL and give his spot on the 40-man roster to Simeon Woods Richardson, who was acquired from the Twins on Wednesday.
