ALLEN PARK, Mich. -- Three weeks after having a career-best performance, enigmatic receiver Titus Young is back in the Detroit Lions doghouse.
Coach Jim Schwartz announced Monday that Young will be inactive for Thursdays game against Houston.
Young also was benched for the final possession of Sundays 24-20 loss to Green Bay.
His behaviors going to have to change, Schwartz said. This is a team sport, its not an individual sport. Eventually, theres no more opportunities to get it right.
Its not the first time the Lions have had to discipline Young, a second-round draft pick in 2011. Young was also told to stay away from the practice facility for a while during off-season workouts after sucker-punching teammate Louis Delmas.
Young appeared to be on the right track when he caught nine passes for 100 yards and two touchdowns in a victory over Seattle on Oct. 28.
But his immaturity problems returned.
Schwartz wouldnt be specific about exactly what Young did wrong.
When you play a game like football, its a team sport, Schwartz said. Players have obligations to the team.
Titus hasnt done a very good job of fulfilling those obligations this week and recently.
Schwartz said he wasn't officially classifying it as a suspension at this point; however, Young was sent home and didnt practice.
Schwartz said he didnt expect Young, who wasnt available for comment, to practice Tuesday, either.
How we go in the future is going to depend on Titus and his behavior, Schwartz said. I think in spots we have seen progress, but in this case, its disappointing. I thought we were past this but obviously were not.
Schwartz confirmed that a false-start penalty on offensive tackle Gosder Cherlius occurred largely because Young didn't line up in the right position on the play.
That was one of the issues, Schwartz admitted. Titus was lined up in the wrong spot in that case and it caused a lot of confusion.
But the situation, obviously, is much bigger than one misalignment.
Until Young figures out the right and wrong way to act in a NFL environment, his future is going to be in question.
Schwartz also addressed the heated verbal exchange on the sideline Sunday between receivers coach Shawn Jefferson and offensive coordinator Scott Linehan.
The dispute reportedly involved Young, but Schwartz wouldnt confirm that aspect of the incident.
Schwartz said run-ins between coaches arent uncommon in an emotional sport like football, but that theyre usually handled differently, quite often over the headsets.
In this case, it was done very publicly," Schwartz said. "Thats regrettable.
Those guys are fine. Theres no issues. The thing about it is they were both on the same side of the argument, but in the heat of the moment, they ended up missing that fact.
Cornerback Drayton Florence woke up with a headache Monday morning and was diagnosed with a concussion.
He played in 43 of the 62 defensive snaps.
He left early in the game, Schwartz said. The official removed him from the game. Our guys (doctors) checked him. He passed all the (concussion) tests on the sideline. He returned to play, played pretty well.
Didnt have any signs as we went forward, didnt seek any treatment, wasnt having any symptoms after the game.
This morning, he woke up with a headache. Our guys diagnosed him with a concussion.
Offensive tackle Jeff Backus, who has played in 186 consecutive games in his career, could have his streak come to an end.
Backus left Sundays game with a hamstring injury.
Its probably going to be doubtful that hell be able to play on a short week like this, Schwartz said.
