Curtis Martin will miss at least the first six weeks of the season. It could be the end of the 33-year-old running back's career.
The NFL's No. 4 career rusher, who underwent knee surgery last December, was placed by the New York Jets on the regular-season physically unable to perform list on Tuesday. That means he will miss the first six weeks and the Jets will have 21 days to decide whether to activate him.
Another star running back, Priest Holmes of the Chiefs, was put on the same list on Monday.
The Jets also announced that Chad Pennington is their starting quarterback. Pennington, who has undergone shoulder surgery for two straight years, had been the starting QB throughout the preseason. But first-year coach Eric Mangini had not designated a starter from among Pennington, Patrick Ramsey, Brooks Bollinger and rookie Kellen Clemens.
J.P. Losman will start the season as the Bills quarterback after beating out Kelly Holcomb and newcomer Craig Nall.
Losman began last season as the starter, but was 1-3 and was replaced by Holcomb.
