Dolphins linebacker Junior Seau is out for the season with a calf injury, but said he plans to return for a 17th season in 2006, even if it's with another team.

The loss of Seau further depletes a linebacking corps already missing Zach Thomas, who is expected to be sidelined two games with a shoulder injury. The Dolphins (3-7) play Sunday at the Raiders.

Seau played the past three games knowing there was a chance he could rupture his Achilles' tendon because of the calf injury, which began bothering him in September. The decision to put him on injured reserve was made after he underwent an MRI exam.

"I played on one leg for seven weeks," Seau said. "Knowing I could have two legs next year, it's definitely something I'm looking forward to."

A 12-time Pro Bowl selection with the Chargers, Seau turns 37 in January and is under contract to earn $2.1 million in bonuses and base salary.

"I'll be back," he said. "It might not be here, but I'll be back."

* CHARGERS: Tight end Antonio Gates practiced yesterday, his first workout with the team since spraining his right foot last weekend. Gates, who has 56 catches for 784 yards and seven touchdowns, was upbeat about his chances of playing Sunday at Washington.

* CHIEFS: Kansas City signed cornerback Alphonso Hodge to a three-year contract. To make room for Hodge on the roster, the Chiefs placed defensive end Khari Long on their practice squad.

Hodge joined the Chiefs as a fifth-round pick in this year's draft. After being released, he spent the first 10 weeks of the season on the practice squad.

* EAGLES: Philadelphia, already without quarterback Donovan McNabb and all-pro cornerback Lito Sheppard, could be without three starters on their offensive line Sunday against the Packers.

Tackle Tra Thomas (back), left guard Artis Hicks (knee) and guard Shawn Andrews (shoulder) missed practiced. Wide receiver Greg Lewis (elbow) also is questionable.

* BILLS: Tight end Mark Campbell missed his second straight practice because of a hamstring injury and is questionable to play Sunday against the Panthers.

Also questionable are two other starters, defensive tackle Sam Adams (ankle) and cornerback Terrence McGee (hamstring).
