Police say Walker attack a robbery

Large amount of cash, jewelry taken

Raiders wide receiver Javon Walker remained hospitalized with a concussion and a battered face yesterday, one day after he was beaten, robbed, and left unconscious on a Las Vegas street after a night of partying.

Police said a large amount of cash and some jewelry were taken from Walker, who suffered "a moderate concussion and significant injuries to his face."

Police Lt. Clinton Nichols said detectives are retracing Walker's activities in the hours before he was found injured Monday morning on a street off the Strip.

"That's one of the first things we do, backtrack what he did and where he stayed," Nichols said, adding that the investigation was still in the early stages.

According to reports yesterday in the Las Vegas Review-Journal, Walker visited a nightclub, Tryst, at the Wynn Las Vegas resort Saturday night. He spent Sunday night at another club, Body English at the Hard Rock hotel-casino, before leaving about 3:30 a.m. Monday, according to a casino spokesperson.

Nichols said detectives spoke briefly with Walker Monday and planned a second interview last night at Sunrise Hospital and Medical Center.

Owens not on hand

Terrell Owens wasn't on the field for the start of the Cowboys' mandatory offseason minicamp, and the Pro Bowl receiver isn't expected to be around the rest of the week. Coach Wade Phillips said Owens was excused from the three-day minicamp to attend to a personal family matter out of town. "He didn't want to go into it, and I really don't want to either," Phillips said. "It's a family matter and just leave it at that. It's not anything more than that." Owens was at the Valley Ranch facility yesterday morning but then left before the first of the team's two practice sessions to catch a flight. Phillips said Owens talked to him Monday, but he wouldn't elaborate on that conversation or where Owens was going.

Glenn wants release

A report on ESPN.com said another Cowboys receiver, Terry Glenn, has refused to agree to a $500,000 injury waiver, the amount the team wants to give him instead of his scheduled $1.74 million base salary this season if he reinjures his right knee and is unable to play again. Glenn said he wants to be released if he continues to be barred from preparing for the season in an attempt to force him to sign the waiver . . . ESPN.com, citing a source close to the Bengals' Chad Johnson, said the controversial wide receiver is scheduled today to have arthroscopic surgery on bone spurs in both ankles that he's needed since last season. Johnson told the team Thursday he couldn't practice because of the injury; the team said he was refusing to practice. Johnson is expected to be ready for training camp.

Simms a no-show

Buccaneers coach Jon Gruden insists his differences with disgruntled reserve quarterback Chris Simms are not personal. Simms, a one-time starter who hasn't played in a regular-season game since rupturing his spleen in September 2006, was a no-show for the start of the Bucs' mandatory three-day minicamp. The sixth-year pro has described his soured relationship with Gruden as beyond repair and would like to be released so he can try to revive his career with another club. "He said what he said. I don't agree with all the things he said," Gruden said about Simms's remarks that he felt mistreated and no longer could play for the coach . . . The Falcons released safety Jimmy Williams, two years after trading up 10 spots to pick him in the second round of the draft. "It's a football decision," new Atlanta coach Mike Smith said. "It's a decision we made, and one that we've been evaluating." With only seven career starts in 27 games, Williams made a poor first impression on Smith, who demoted the former Virginia Tech standout to third string after he reported to a voluntary minicamp nearly 20 pounds overweight. Williams skipped the next two days of the camp, but despite falling behind Erik Coleman and rookie Thomas DeCoud on the depth chart, he was at every team session before yesterday. "I wasn't sure it would [get to this point]," Williams told the Daily Press of Newport News, Va. "They've been upset with my weight, but I didn't think the weight thing was a big issue. I thought they were hiding behind that."

Tatupu plea

Seahawks linebacker Lofa Tatupu entered a plea of not guilty in Kirkland, Wash., to charges of driving under the influence of alcohol. Tatupu appeared before Kirkland Municipal Court Judge Michael J. Lambo but did not speak. His attorney, Jon Fox, told the judge his client would plead not guilty. After the hearing, Fox told reporters that Tatupu would not make a statement or answer questions. Lambo set a tentative court date for July 7. Training camp opens July 25. Tatupu was stopped in the Seattle suburb, the home of the Seahawks' headquarters and practice facility, at 2 a.m. May 10 for traveling more than 15 miles per hour above the posted 35-m.p.h. limit . . . Former Bears fullback Roland Harper admitted in US District Court in Chicago he acted as a front man in a fraud involving a $1.5 million Chicago Public Schools landscaping contract reserved for minority firms. Harper, 55, pleaded guilty to a single count of mail fraud.

Haynesworth in limbo

The agent for All-Pro defensive tackle Albert Haynesworth doesn't think a long-term deal with the Titans will be reached before the July 15 deadline. "There has been no significant movement from the Titans on a long-term deal since prior to the Combine in February and I don't think this will change before July 15," Chad Speck said in an e-mail . . . Jay Cross resigned as president of the Jets after eight years with the team to accept a position as president of Related Hudson Yards.
