Manager Matt Quatraro said that Avila is scheduled to undergo Tommy John surgery on his right elbow Wednesday, Joel Goldberg of Bally Sports Kansas City reports.
The 24-year-old was placed on the injured list Sunday due to forearm tightness, and further evaluation apparently revealed a torn UCL. Avila will miss the rest of this year and is also likely to be sidelined for the full 2027 season. He made 21 appearances (12 starts) for Kansas City prior to the injury and had a 5.53 ERA, 1.61 WHIP and 61:42 K:BB over 70 innings this season. Avila will likely be shifted to the 60-day injured list in the near future.
