ALLEN PARK, Mich. -- Detroit Lions left tackle Taylor Decker will be out indefinitely after having surgery on his shoulder Monday, following an injury last week.
The team's first-round pick last year, Decker started every game of his rookie season. He played every snap at left tackle and had been expected to be an anchor of the Lions' offensive line this upcoming season.
Lions coach Jim Caldwell, in announcing the surgery, said he didn't think the injury would keep Decker out for all of the 2017 season. Caldwell did not have a possible timetable for recovery, saying the team would provide an update during training camp -- but that Decker would be out for the rest of OTAs and minicamp.
Caldwell also declined to say how the injury occurred. He said "sometimes they are noncontact injuries. I didn't say this was one of them, but I'm just talking about it doesn't require that there's any force contact for that to happen."
Thanks to the best fans, friends, and family for the well wishes!

Decker participated in the Lions' open organized team activity last Wednesday. Caldwell said that his team followed the rules, but "things happen sometimes in practice."
"Any time that you've had surgery, you just don't know details," Caldwell said. "So like I said, we'll update you in the fall."
Caldwell didn't seem too concerned about how missing time would stunt Decker's development, mostly because of how well he played as a rookie.
At the Lions' open OTA on Tuesday, both Joe Dahl and Cornelius Lucas took reps at left tackle. They are the two likely in-house replacements for him. Corey Robinson, who would also be a candidate there, was not present at OTAs for the third straight week.
Neither Dahl nor Lucas spoke to the media after practice.
Caldwell also didn't rule out investigating free-agent options at left tackle.
"Just kind of the nature of our game," Caldwell said. "You've got to adjust. That's one of the things that I think our personnel office does a great job of, I think our players do a tremendous job of. We'll adjust and keep moving."
