FLORHAM PARK, N.J. -- New York Jets fullback Tommy Bohanon broke his collarbone in the team's 24-17 loss to the Detroit Lions, but played the entire second half before being diagnosed.

"That obviously is a major injury, we'll bring some guys in, we'll see how that progresses," Jets coach Rex Ryan said.

Ryan announced the injury during his Monday news conference, and said the team will wait for a second opinion on Tuesday before deciding whether to place Bohanon on reserve/injured. The fullback was drafted in the seventh round of the 2013 draft.

The Jets had a few other injuries during the game. Wide receiver David Nelson has a sprained left ankle, but Ryan was unsure how severe the injury is. "The fact that he didn't finish the game will lead you to believe that it's a pretty good ankle [injury]," Ryan said.

Ryan said top wide receiver Eric Decker came through the game well after working through a hamstring injury the past two weeks.

"He feels better today than he did this time last week," Ryan said.

As for the secondary, the Jets got some good news. After a scare in the lockerroom postgame, Ryan said Antonio Allen wasn't hurt. "My understanding is he's fine."

Cornerback Dee Milliner, who missed the last two games with a quadriceps injury, is expected to return this week. Ryan said he's "confident" the former first-round pick will be ready.

Rookie safety Calvin Pryor has a thigh contusion, but it's not as severe as initially thought. "It's not as swollen as we thought it would be, so that's a positive sign," Ryan said.

Defensive lineman Damon Harrison has an ankle injury, but returned to the game.
