Mathis trying to return Sunday vs. Bengals

ALLEN PARK, Mich. -- Detroit Lions cornerback Rashean Mathis, who left Sunday’s win against Cleveland with an injured groin, said Tuesday he will be doing “everything I can do” to return Sunday against Cincinnati.

The Lions could definitely use Mathis, as they face elite wide receiver A.J. Green. Cornerback Chris Houston, who had a hamstring injury earlier this season, will likely draw the assignment of Green, but Mathis could be matched up on him as well.

“I feel good. Moving fine,” Mathis said. “Just doing everything I can do to be ready, to try and be 100 percent or close to 100 percent come game day.

“So treatment, treatment, treatment. Rehab, rehab, rehab. And we’ll see.”

If Mathis does not play Sunday, he’ll be replaced by rookie Darius Slay, who filled in for him Sunday against Cleveland and earlier this year against Chicago. Slay initially won the cornerback job out of training camp, but was replaced by Mathis before Week 3.
