Hawks rookie John Collins is expected to miss two to three weeks of games with a Grade 2 sprain in his left shoulder. Collins suffered the injury near the end of the Hawks’ loss to the Cavaliers on Thursday night.

An MRI performed Friday morning confirmed the Grade 2 sprain which, according to Harvard Medical School, is the complete tear of one ligament in the joint and a partial tear of another. Collins shoots with his right hand.

The Hawks selected Collins, 20, with the No. 19 overall pick the 2017 draft out of Wake Forest. In 21 games Collins has averaged 11.5 points and 7.1 rebounds while shooting 59.2 percent from the field.

Collins has played primarily at center. He started the past three games because of injuries to Luke Babbitt and Dewayne Dedmon.
