Berrios (elbow) will report to Single-A Dunedin on Thursday to begin a rehab assignment, Arden Zwelling of Sportsnet.ca reports.
The veteran right-hander is scheduled to throw about 50 pitches across three innings, and he may not require a lengthy rehab assignment before being cleared to come off the injured list. Berrios didn't seem to have a guaranteed rotation spot during spring training given Toronto's offseason additions, but he should get that opportunity based on the injuries the Blue Jays have dealt with early this season.
