Cubs All-Star left-hander Matthew Boyd is scheduled for the first of two rehab starts on Sunday

Chicago Cubs left-hander Matthew Boyd is scheduled to make the first of what is expected to be two rehab starts for Triple-A Iowa on Sunday, the team said Tuesday.

Boyd has been on the injured list since May 4 with a torn meniscus in his left knee that required surgery. He was injured when he sat down on the floor to play with his children.

Boyd is 2-1 with a 6.00 ERA in five starts this season. He was selected to the All-Star Game for the first time in his 12-year career last season.

Boyd threw a 52-pitch simulated game prior to Tuesday night’s game against the Pirates.

The backstory:

Boyd had an MRI in early May that showed a meniscus issue, and manager Craig Counsell said at the time the team wasn't sure how long the left-hander was going to be out.

The 35-year-old Boyd, who started for the Cubs on opening day, is 2-1 with a 6.00 ERA so far this season. He was activated from the 15-day IL on April 22 after being sidelined by a biceps strain.

Counsell said then Boyd got hurt when he sat down with his kids and got back up.
