New York Jets? running back Curtis Martin could be ready to go this Sunday after an MRI taken on his injured right knee came back negative, meaning there are no ligament tears. Martin will likely be listed as questionable and will be "day-to-day" in terms of practice, which he won't today. It'll likely be a game-time decision whether he plays Sunday. "He's been a workhorse," Jets? coach Herman Edwards said. "He's been a guy that's always answered the bell. We'll just see where he's at."
