It’s been a month since Zach Orr announced his comeback to the NFL and the former Baltimore Ravens linebacker still hasn’t found a job.

Detroit Lions coach Jim Caldwell was diplomatic when asked about Orr at his season-opening news conference Saturday, calling the second-team All-Pro a proven talent but stopping short of saying he passed his physical with the Lions.

Orr retired in January because of a spinal condition in which the vertebra at the top of his neck is not fully formed.

Detroit Lions crazy to talk about winning Super Bowl this season

Lions' Matthew Stafford has private QB coach; will it lead to wins?

He consulted with several specialists who he said gave him the OK to resume his career this spring, took his first free-agent visit to the Lions in late June and has visited a handful of teams since.

“I don’t think you never say never in situations, because you just don’t know what’s going to happen,” Caldwell said. “What’s going to happen with your team, injuries and those kinds of things, you just don’t say it. But I’m focused in on who we have here. We think we have a really good core here and we’re looking forward to getting those guys out on the field.”

The Lions, for now, appear to have a full complement of linebackers on their 90-man roster, with rookie Jarrad Davis expected to start at middle linebacker and Tahir Whitehead cleared to practice after sitting out spring drills with a knee injury.

Paul Worrilow, fourth-round pick Jalen Reeves-Maybin and Antwione Williams also will compete for starting jobs, Thurston Armbrister and Nick Bellore could fill special-teams roles, and the Lions remain high on Steve Longa.

Orr led the Ravens with 132 tackles and had three interceptions last season.

Asked what Orr can provide a team, Caldwell said, “I’m not real certain. Obviously, you know he has talent, we know that. And certainly he’s proven that in this league. We took a look at him like we do a lot of guys. We bring them in, we work them out, we do all our due diligence and we just kind of go from there. At this point in time, obviously, we’re focused in on the guys that we have here.”
