Defensive end Richard Seymour missed practice Tuesday for the second straight day, and he still hasn't given any public indication on whether he intends to honor the trade by the New England Patriots.
Raiders coach Tom Cable said he remains hopeful that Seymour will show up as soon as he gets his affairs in order.
"I don't want to comment on (Seymour's status) until we have something that's done and concrete," Cable said.
The deal was done Sunday, as far as the NFL and the Patriots are concerned. The league approved the trade Sunday afternoon, and Patriots coach Bill Belichick already has filled Seymour's roster spot.
"We don't have the rights to Richard, so I can't really speak to that," Belichick told reporters in Foxborough, Mass., in his first public comment since the trade. "There isn't really anything I can say about him or his situation. I'll pass on that."
It's up to the Raiders to set a time frame for Seymour to report. The Collective Bargaining Agreement doesn't require a traded player to report to his new team by a certain time.
Therefore, the Raiders can be as patient as they want with Seymour, though Cable said he would like to have Seymour in uniform for the regular-season opener Monday night.
"This is an issue between the clubs," said Greg Aiello, the senior vice president of public relations for the NFL. "Any comment on the situation at this time would have to come from the clubs."

Raiders linebacker Ricky Brown said Seymour shouldn't listen to those who tell him that Oakland isn't a desirable team to play for.
"He doesn't know what's been going on here since the offseason program started in March "... ," Brown said. "When he comes around, he's going to realize that the perception and reality are completely different."
Seymour played on Patriots teams that went 77-19 the past six seasons. The Raiders were an NFL-worst 24-72 during that time.
Raiders linebacker Thomas Howard said the addition of Seymour would transcend his play on the field.
"He could bring so much to this locker room with leadership, like Greg Ellis did," Howard said. "He's a guy who's known for playing the run exceptionally well. And we've had issues with that; there are no secrets behind that. So, hopefully, he can come in here and help us."
Cable said Asomugha is able to do everything required of him to play in a game.
