Detroit Lions cornerback Emmanuel Moseley suffered a torn pectoral muscle in practice this week and is out indefinitely, sources told ESPN's Adam Schefter.
It marks the third consecutive season that Moseley has suffered a major injury.
After missing the final 12 games of the 2022 season because of a torn left ACL, Moseley appeared in only one game with the Lions last season because of a torn ACL in his right knee.
Moseley was transitioning away from outside cornerback during training camp and competing with Amik Robertson and Ifeatu Melifonwu for Detroit's primary nickel cornerback spot.
