The Detroit Lions' revamped offensive line took a big hit.
Coach Jim Caldwell announced Tuesday that left tackle Taylor Decker underwent shoulder surgery Monday after suffering an injury last week during non-padded organized team activities.
Caldwell did not give a timetable for Decker's return. The coach said he would update the second-year player's status at the start of training camp. Caldwell added he doesn't think the surgery should cost Decker his entire 2017 season.
It's a blow for Decker, who is coming off a promising rookie campaign. Decker anchored Matthew Stafford's blindside last season, allowing 4.5 of 37 team sacks allowed. The Lions expected the left tackle to further improve in Year Two, solidifying a line that added highly paid right tackle Ricky Wagner and guard T.J. Lang.
Caldwell said Wagner would remain at right tackle. Joe Dahl, Corey Robinson and Cornelius Lucas are candidates to replace Decker on the left side. Dahl played with the first team in Monday's practice, per the Detroit Free Press.
