Hutchison has been out since June 15 with a sprained ulnar collateral ligament in his right elbow. He was expected to be out for six weeks and the latest rehab plan puts him on schedule for that timeline.
The 21-year-old made 11 starts for the Blue Jays this season and went 5-3 with a 4.60 ERA. Manager John Farrell said it was premature to speculate on when Hutchison will be able to make a return to the mound.
Toronto also got some more encouraging news on right-hander Brandon Morrow.
The 27-year-old threw 30 pitches in live batting practice at the club's Minor League complex in Florida on Wednesday and as expected has been cleared to make his first official rehab start this weekend for Class-A Dunedin.
"Now it's just a matter of taking the next progressive step, which would be a rehab start Sunday with Dunedin," Farrell said. "In just talking with him this afternoon, he's going to need repetition to get his command back and his release point re-established. Physically, a good day for him."
Morrow has been out since June 13 with a strained left oblique muscle. He is 7-4 with a 3.01 ERA and 67 strikeouts in 77 2/3 innings this season.
