MLB Injury Report: Andrew Vaughn sidelined with hamate fracture, Nick Lodolo aiming to return next week

The MLB Injury Report will be bringing you all of the relevant injury updates from around the league over the last week, all in one place. It was a relatively quiet first week of baseball on the injury front. This first edition is highlighted by Andrew Vaughn’s hamate fracture, set to sideline him 4-6 weeks, and Nick Lodolo is ready for a tune-up start in the minors before his return next week.

We break down those situations and more here. Let’s get started. ⚾️  Baseball is back!

MLB returns to  NBC and Peacock in 2026 ! In addition to becoming the exclusive home of Sunday Night Baseball, NBC Sports will broadcast MLB Sunday Leadoff, “Opening Day” and Labor Day primetime games, the first round of the MLB Draft, the entire Wild Card round of the postseason, and much more. Merill Kelly (back) Kelly was placed on the injured list after getting a late start to his build-up this spring due to nerve issues in his back.

He had already made a pair of spring training appearances, but he will need a couple of rehab starts as he gets his pitch count up. The first start of his rehab assignment is scheduled to come this Friday with Triple-A Reno, putting him on track to return to the Diamondbacks’ rotation in mid-April, likely replacing either Michael Soroka or Brandon Pfaadt. Soroka impressed in his first start of the season on Monday, striking out ten over five shutout innings against the Tigers in Arizona.
