The Angels placed Loup on the 15-day injured list Friday with a left shoulder strain, Jeff Fletcher of The Orange County Register reports.
Loup's injury will put an early end to his 2023 campaign. He finishes with a 6.10 ERA and 1.75 WHIP through 48.2 innings while also notching a save and nine holds. Davis Daniel will come up from Triple-A Salt Lake to fill Loup's roster spot.
