Geno Smith jogged across the practice field shortly before 10 yesterday morning. He had sprained his right ankle less than 48 hours prior but the Jets rookie quarterback refused to let that keep him off the field.

“I felt it was important just to practice” Smith said. “You can’t miss a day of practice. I pride myself on being out there at all times and one little ankle injury wasn’t going to keep me from practicing and competing with my teammates.”

Smith had a noticeable limp and offensive coordinator Marty Mornhinweg rode him in practice repeatedly yelling at him “Don’t limp don’t limp!” Smith’s drop-backs were slower and he did less running than usual but he had a strong practice overall.

Smith said the X-rays and MRI exam showed no damage to the ankle after he got his foot caught in the turf during Friday night’s 26-17 loss to the Lions in Detroit. He would not even describe it as a sprain.

Smith is competing with Mark Sanchez for the starting job and said he has no plans of missing any practice. Something Mornhinweg told him about a former Jets quarterback stuck with Smith.

“He told us about Brett Favre and the way he played through every single injury” Smith said “so I try to be the same way.”

There was a thought the Jets should hold Smith back for a day or two and let his ankle heal more but coach Rex Ryan said as soon as Smith was cleared by the trainers he was going to practice.

“That’s not my job” Ryan said. “My job is to coach. I lean on our trainers who are experts. So I’m going to lean on them I’ll lean on our medical department with any injury. When they say the young man is cleared to participate then that’s exactly what’s going to happen.”
