Blue Jays C Alejandro Kirk (left thumb) headed for surgery Tuesday

Blue Jays catcher Alejandro Kirk will undergo surgery on Tuesday to repair his broken left thumb, Toronto manager John Schneider said Monday.

The two-time All-Star was injured during Friday's 5-4 loss to the Chicago White Sox when he caught a foul tip near the bottom of the glove. The club hasn't yet determined how long Kirk will be sidelined.

"We'll know the timeline after the surgery," Schneider said.

Kirk, 27, is 3-for-20 (.150) with a homer and two RBIs in five games this season.

In seven big-league campaigns, Kirk is batting .267 with 52 homers and 265 RBIs in 569 games since reaching the majors with the Blue Jays in 2020.

Tyler Heineman, 34, who is 4-for-10 in five games this season, is slated to be the main catcher while Kirk is out. Prospect Brandon Valenzuela, 25, was recalled Saturday from Triple-A Buffalo to be the backup and was 1-for-3 with two strikeouts on Sunday in his major league debut.
