The 27-year-old was struck on the thumb of his glove (left) hand on a foul tip off the bat of Chicago White Sox outfielder Austin Hays in the 10th inning of Friday’s series opener.
In 20 at-bats in 2026, Kirk had three hits, one home run, and two RBI.
Kirk played in 130 games last season, hitting .282 with 15 home runs, 76 RBI and 45 runs scored as he was named to his second career All-Star team.
Brandon Valenzuela, 25, started the season in Triple-A and was recalled in Kirk’s place. He went 1-for-3 with a single in his MLB debut in Sunday’s series finale against the White Sox.
Blue Jays select Fleming
The Jays also selected left-handed pitcher Josh Fleming to the Major League roster and designated right-handed pitcher Austin Voth for assignment.
Fleming will be available for Monday’s series opener against the Los Angeles Dodgers at Rogers Centre, a rematch of last year’s World Series.
The 29-year-old Fleming last pitched in the MLB during the 2024 season, posting a 4.02 ERA over 25 appearances, including three starts, for the Pittsburgh Pirates. Fleming has a 4.77 ERA over 80 games with the Tampa Bay Rays and Pirates.
Voth, 26, made one appearance this season for the Jays, allowing one earned run over 2.2 innings of work during Sunday’s loss to the Chicago White Sox.
After sweeping the Athletics to open the season, the Blue Jays have dropped five of their last six games, including a three-game sweep by the White Sox this past weekend, to fall to 4-5 in 2026.
