ALAMEDA, Calif. (AP) -- Five-time Pro Bowl defensive lineman Richard Seymour did not report to the Oakland Raiders on Monday, a day after being acquired in a trade with the New England Patriots.
Raiders coach Tom Cable said after practice that Seymour had to resolve some things with the Patriots before the deal for a first-round pick in 2011 could be finalized.
"We have attempted to make a deal," Cable said Monday. "There are some issues still between him and the Patriots that are being worked out. I'm hoping that that will get resolved as quickly as possible. We know that the player wants to be here, but we have really no control over those issues."
Patriots spokesman Stacey James said he was unaware of any difficulties surrounding the trade, which was announced by New England on Sunday and confirmed by Cable.
Cable did not want to address the issue further Monday, but said Seymour told him he wants to be in Oakland. Cable did not say when Seymour would have to arrive in order to be able to play in the season opener next Monday night against San Diego.
"Just as soon as possible. That's really the only way to answer that right now," he said.
Seymour, who turns 30 next month, is in the final year of a contract that pays him about $3.7 million this season. The deal would send him from a team that has gone 77-19 the past six seasons and is a perennial Super Bowl contender to one that is an NFL-worst 24-72 over that span.
Seymour has been a stalwart in New England since being drafted sixth overall in 2001. He played on three Super Bowl winners with the Patriots, recording 39 career sacks and being selected to the Pro Bowl for five straight seasons beginning in 2002.
The Raiders were looking to upgrade a run defense that was the worst in the league during the exhibition season and has been the worst over the past six seasons. Since going to the Super Bowl following the 2002 season, Oakland has had the worst run defense in the NFL, allowing 141.7 yards per game on the ground and 122 touchdowns rushing. The Raiders have allowed a 100-yard rusher in more than half of their games the past three years.
