Pearson (groin) is slated to make his third rehab outing with Triple-A Buffalo on Sunday, Ben Nicholson-Smith of Sportsnet.ca reports.
Pearson tossed a perfect inning in both of his first two games with Buffalo, and he's set to make at least one more appearance before potentially joining the Blue Jays' bullpen. If Sunday does indeed mark Pearson's final rehab outing, he could join Toronto at some point during an upcoming four-game series against the White Sox that begins Monday.
