Atkins said that Pearson was injured in his first spring training start Monday against the Pittsburgh Pirates. No specific timeline for his recovery has been determined yet but Atkins said "we don't expect for him to miss too much time."
"Our goal and hope is that you're seeing him again here in spring training pretty quickly," Atkins added. "But we will be cautious because we can and we'll make sure that that pain is completely gone before he's back on the mound. Whether that's a week or a couple of weeks or longer is too hard to say at this point."
Pearson was scheduled to throw two innings against the Pirates but only threw one after needing 28 pitches to get out of the inning, allowing one earned run.
The 24-year-old is expected to be a regular part of the Blue Jays rotation this season, his first full campaign in the majors. Elbow injuries limited Pearson to only four starts and five appearances last season and he posted a 6.00 ERA with 16 strikeouts in 18 innings.
