Jets running back Curtis Martin won't practice when training camp opens Friday because of a lingering knee injury. Martin was placed on the physically unable to perform list Thursday, along with Justin McCareins and Trey Teague. The 33-year-old Martin had arthroscopic surgery last December to clean out his right knee, then was limited during minicamp last month. Though the surgery wasn't considered invasive, it has taken Martin some time to recover. Martin and coach Eric Mangini were unavailable for comment Thursday, when players reported for camp.

The Jets on Wednesday night signed offensive tackle D'Brickashaw Ferguson, the fourth overall pick in April's NFL draft. Terms were not disclosed.

Pro Bowl cornerback Ty Law agreed to a five-year deal with the Kansas City on Sunday.

The New York Jets signed third-round picks Eric Smith and Anthony Schlegel and fourth-round pick Brad Smith on Friday. Eric Smith, a 6-foot-1, 209-pound safety, posted over 100 tackles in each of his last two seasons at Michigan State. His 323 career tackles rank 13th in school history, and he posted 13 games with double-digit tackles as a Spartan.

Quarterback Patrick Ramsey, acquired by the Jets earlier this spring to compete with the rehabilitating Chad Pennington for the starting job, has signed a one-year contract extension. The extension, first reported by the New York Daily News, had been under discussion since the Jets added Ramsey in a deal with the Redskins for a sixth-round draft choice. The add-on is worth $2.1 million and includes a $1.4 million roster bonus next spring.

Jets Coach Eric Mangini is saying that every position on the team is available and that includes quarterback. QB Chad Pennington is recovering from an injury and may need to fight to re-acquire his starting position. Backups Patrick Ramsey, Brooks Bollinger and Kellen Clemens are also in the mix.
