The Jets are six weeks into their offseason program, and Richardson has been "in and out," according to Todd Bowles.

"He's been here half the time, half the time he wasn't," said Bowles, adding he has "no idea" why Richardson missed the first two OTAs.

Seattle Seahawks Maillot,It's too soon to panic or draw harsh conclusions -- it's only May -- but you'd like to think every player, especially the best ones, would show up to support their new coach. There's a new system to learn and new teammates to meet. That's in an ideal world, but the NFL is seldom ideal.

"It's voluntary, so there's not much you can do," Bowles said.

Wilkerson's absence is contract-related. The Jets have said they'd like to sign him to an extension, but the two sides are talking only "sporadically," owner Woody Johnson told reporters Tuesday at the owners' meetings in San Francisco. Wilkerson is due to make $6.97 million in the final year of his deal. He's expected to skip the remaining OTAs and it wouldn't be a shock if he doesn't show for the mandatory minicamp, which begins June 9. Players can be fined up to $63,000 for blowing off all three days of a mandatory minicamp.

"He's very vital" to the defense," cornerback Darrelle Revis said of Wilkerson. "He's one of the best defensive linemen in the league. He shows it every time he goes out there and plays. But he has his own situation and management will do what's best for the team."

Wide receiver Brandon Marshall also didn't attend Wednesday, but he notified Bowles and is expected to practice Thursday.

In injury news, wide receiver Jeremy Kerley (ankle/Achilles') sat out, as did safety Marcus Gilchrist (shoulder). Quarterback Ryan Fitzpatrick (leg), running back Stevan Ridley (knee) and cornerback Dee Milliner (Achilles') were limited, among others.
