INDIANAPOLIS -- The Detroit Lions might have to replace the right side of their offensive line over the next couple of weeks but don't expect a youth movement if the team loses right guard Larry Warford and right tackle Riley Reiff.

Lions general manager Bob Quinn knows the team can't have a completely young unit up front protecting quarterback Matthew Stafford. Considering left tackle Taylor Decker and left guard Graham Glasgow are heading into their second seasons, it would seem Detroit is hoping to have at least one veteran -- if not more -- on the right side of the line.

"It's very important. You can't have all rookies and second-year players on your offensive line. That's something that is a philosophy of mine," Quinn said. "You can't go too young."

Quinn said he's had discussions with representatives for both Reiff and Warford and "we don't have anything to announce [Wednesday] but we're working towards that." That, of course, is no guarantee the Lions bring back either player considering free agency begins in a week and the market for both players should be fairly strong.

Warford is considered one of the best guards on the market and Reiff could benefit from a weak tackle class both in free agency and the draft.

If the Lions were to lose Warford, Joe Dahl and Laken Tomlinson would likely compete for that spot. Of course, if Dahl won the role, that would put another player without much experience starting on the line.

At tackle, there are not many sure-fire options for upgrades outside of Reiff. Ricky Wagner would be the biggest draw on the market, but after that there might not be many better than Reiff. The tackle class in the draft has some first-round prospects, but none that are obvious upgrades from Reiff.

Plus, Reiff's presence would give Detroit at least two veterans on the line as center Travis Swanson has been cleared to resume all activities and should fully participate in the Lions' offseason program as he enters a contract year. But there's clearly no guarantee Reiff will return because many teams need tackles and that might drive the price up.

The thin class could affect what the Lions decide to do, though. The Lions don't have much depth at tackle other than Decker and Corey Robinson, who served as the team's sixth offensive lineman when healthy last year.

"It factors in," Quinn said. "You got to look at not only the perceived lack of depth in the offensive line in this year's draft. There might be some guys in the middle rounds that might be a little bit undervalued that could rise through the process here in the next month or so.

"But we look at that and who might be available next season in free agency. You gotta look at everything."
