Diamondbacks starter Ryne Nelson is back in the rotation with Corbin Burnes' season-ending elbow injury. But first, Friday's suspended game resumes.

The Diamondbacks ace was diagnosed with a torn ulnar collateral ligament (UCL) in his right elbow, manager Torey Lovullo said Friday, and as a result, Burnes, 30, will need to undergo Tommy John surgery. The procedure will be performed by Dr. Neal ElAttrache in Los Angeles.
