FLORHAM PARK, N.J. -- The New York Jets' Dee Milliner didn't practice all week, and coach Rex Ryan said the cornerback was doubtful for Sunday's game against the Detroit Lions at MetLife Stadium due to a lingering quad injury.
"Don't feel really good about that one," Ryan said Friday.
Milliner missed the loss to the Chicago Bears with a quad injury after missing the first game of the season with a high ankle sprain. Milliner had four tackles against the Green Bay Packers, when he was in on 56 percent of the team's defensive snaps.
That's not a lot of time during a 1-2 season in which Milliner was expected to be the Jets' top cornerback. Third-round draft pick Dexter McDougle didn't even make it to the regular season after tearing his left ACL in August.
So the Jets' cornerback situation this season has been fluid.
Antonio Allen has been converted from safety to corner, where he will remain for the duration of the year according to defensive coordinator Dennis Thurman.
"It's cool," Allen said as he tries to adjust to an increased media demand that comes with the starting spot.
"It's altered our depth [at safety] for sure," Thurman said. "The thing that you try to do is you try to put the best 11 football players out there that you can. And the positions they play may not always be exact for some, but you still want your best 11 players on the field and we feel like he's one of our best 11."
Allen has done fairly well in his new role, as has former backup Darrin Walls. Walls had a pass interference call last week that many on the Jets questioned, but for the most part his coaches have given Walls good reviews.
"He's going to be hard to move out of there," Ryan said of Walls.
Walls said he and Allen are developing more confidence as a pair.
"For me it's what I wanted," Walls said. "Everyone coming into the league wanted to be a starter."
The Jets' secondary will face a big test against the Lions and Calvin Johnson. Johnson practiced Friday for the first time all week, but Walls has been expecting him all along.
"I knew he was going to play regardless," Walls said. "He said he couldn't wait to play against us so pretty much figured he was going to play."
