Springer was injured when tracking doing a potential fly ball from Mariners shortstop J.P. Crawford.
The Blue Jays outfielder raced forward from centre field to try and make a catch on the play as Toronto shortstop Bo Bichette ran toward him.
As Springer dove forward it appeared he clipped Bichette and then hit his head hard on the Rogers Centre turf.
Crawford's hit landed for a double to clear the bases and tie the game 9-9.
Both Bichette and Springer lay prone on the field in obvious pain as the crowd fell silent.
