The LenDale White experiment in Seattle is over.

White was released on Friday, and a league source told ESPN's Adam Schefter that he is facing a four-game suspension from the NFL for violating the league's substance-abuse policy.

"We have not announced any such suspension," league spokesman Greg Aiello told The Associated Press on Friday night. "I have no other information on it."

The list of players enrolled in the league's substance-abuse program for a prior incident, and therefore subject to discipline, is confidential.

Acquired from the Tennessee Titans in a trade, White reported to the Seahawks in great shape. He was down to 220 pounds after being 250 pounds at times as a member of the Titans.

"It became apparent at this time that LenDale was not ready to be a member of the Seattle Seahawks," Seahawks GM John Schneider said. "It just did not appear to be the right fit at this point in our program. We wish LenDale all the best with his future."

White came to the Seahawks during the third day of the NFL draft. The team also acquired defensive tackle Kevin Vickerson.

The trade reunited White with Seahawks coach Pete Carroll, whom White played for at USC.

White's uncle said his nephew is "confused" and not doing well with the Seahawks' decision.

Herman White told The Associated Press in a phone interview Friday night that he's been speaking with the former USC star throughout the day and that "he wasn't doing good."

The uncle White said he did not know if White was facing a four-game suspension for violating the league's

drug policy. He said he was due to speak to the Titans' former

leading rusher later Friday night or Saturday to find out more.

"He was surprised," Herman White said, adding LenDale told him

this week how great his second NFL chance was going with Carroll. "I'm pretty shocked, based on what

he's been telling me.

"His emotions and all ... he wasn't doing good [Friday]."

The Seahawks gave up on White after he had only limited chances to display his work ethic. He participated in one minicamp and a handful of organized team activities on the practice field before the team waived him.

White had lost more than 45 pounds last year, saying that when he stopped drinking tequila the pounds starting falling off. He was down to 220.

White said he wanted to get back up to 228 pounds for this season. Seattle's starting job seemed within his reach as Carroll opened every position to competition.

He missed one day of organized team activities this month. He said on Monday there was some "family stuff I had to take care of."

Agent Drew Rosenhaus did not immediately return phone and e-mail messages left by The Associated Press. He was on the phone late Friday afternoon with his client sorting out a confusing sequence in which the Seahawks put out an announcement on their website around noon that White had been released, only to take it down soon after.

Hours later, Schneider made it official in a statement released by the team.

Earlier this week, White said he felt great. He thanked Carroll for rescuing him from his dead end in Tennessee.

"Going from 'SC, back-to-back national championships to not playing at all, it's a life-changing thing," White said Monday. "But I'm still here. Pete gave me another chance.

"I don't think I've been this healthy since I was 18 years old."

Carroll said Monday that the team would see how everything fit together. "He's got a long ways to go to get back in here with this club, but we're going to certainly wait it out and see how it does," he said.

The wait lasted all of four days.
