Bo Bichette of the Toronto Blue Jays is expected to miss “multiple weeks” because of a strained right calf, manager John Schneider announced on Saturday.

In the sixth inning of Friday’s 5-4 defeat to Detroit, Bichette—who has twice been an All-Star and twice led the AL in hits—injured himself while sprinting to first base. After taking a few steps, he became uncomfortable and was clearly in agony as he hopped before he and the trainer left the field.

The Blue Jays activated utility man Addison Barger from Triple-A Buffalo and put Bichette on the 10-day disabled list before to their 7-3 defeat to the Tigers on Saturday.

On June 24, Bichette was activated from the disabled list following nine games missed because of a right calf strain. Due to calf pain, he had also exited a game against San Francisco on July 10 and missed the last four games before to the All-Star break.

Bichette, the son of former MLB outfielder Dante Bichette, has had a difficult season. In 79 games, he had a batting average of.223 with four home runs and thirty RBIs; among qualifying AL batters, his.597 OPS is the lowest.
