Lions' Glover Quin evaluated for concussion, Golden Tate injures shoulder

NEW ORLEANS -- The Detroit Lions lost two key players on either side of the ball in Sunday's 52-38 loss to the Saints.

Safety Glover Quin was ruled out after being evaluated for a concussion and wideout Golden Tate exited with a shoulder injury.

Lions coach Jim Caldwell was not certain if any of Detroit's injuries suffered Sunday were long-term. Quin was spotted walking out of the Lions locker room after the game, while Tate had his belongings packed up by an equipment manager.

Quin was injured trying to tackle Saints running back Alvin Kamara on a first-and-10 from the New Orleans 46-yard-line.

When Quin was trying to tackle Kamara, teammate A'Shawn Robinson's knee appeared to collide with his helmet. Quin immediately fell to the ground and didn't appear to be moving for a short period of time.

Quin eventually sat up and was walked, with the help of trainers, immediately to the locker room. As he got up, multiple Lions players went over to check on Quin and pat him on the back for encouragement.

Tate had scored on 45-yard touchdown reception -- that caught the attention of famed WWE wrestler The Rock -- in the first half where he spun to break two tackles and then flipped into the end zone. He finished the day with seven catches and 96 yards with the score.

Quin has been the emotional leader of the Lions' defense. A Pro Bowler in 2014, Quin has started every game since the start of the 2010 season between Houston and Detroit. He had five tackles Sunday at the time of his injury.

Caldwell said sitting defensive end Cornelius Washington was not a disciplinary issue. It's the first time Washington had been inactive all year. Also, he said T.J. Lang's back flared up on him Sunday morning, leading to Emmett Cleary getting the start at right guard. Cleary left the game as well and had his right ankle taped after the game, but said he was fine.
