Atlanta manager Walt Weiss said Friday that Schwellenbach (elbow) lacks a clear timeline to begin a rehab assignment, Chad Bishop of the Atlanta Journal-Constitution reports.
Atlanta had some hope that the 26-year-old right-hander would be able to make his season debut before the end of August, but he'll need to get back into game action in the minors within the next week or two for that to be a realistic possibility. Schwellenbach is recovering from a fractured elbow he suffered last June, having put together a 3.09 ERA, 0.97 WHIP and 108:18 K:BB through 110.2 innings in 2025 up to that point.
