Dallas Cowboys cornerback Adam Jones of West Virginia once again must earn his way back into the NFL, and it likely will take more than being on his best behavior.

The NFL suspended Jones for at least four games yesterday for violating the league's personal conduct policy. Commissioner Roger Goodell will determine the full length of the suspension after the Cowboys' game in Washington Nov. 16.

After repeated legal trouble while with the Tennessee Titans, Jones was traded six months ago to Dallas, where he had stayed out of trouble until an alcohol-related scuffle Oct. 7 with one of his bodyguards at a private party

Roy Williams headed home to Texas in the NFL's biggest trade before the deadline, giving struggling Dallas another proven wide receiver opposite Terrell Owens. The winless Detroit Lions traded their unhappy 2004 first-round pick and one-time Pro Bowler for three draft picks, from the first, third and sixth round in 2009. Detroit also gave up a seventh-rounder next year.

Quarterback Eli Manning sustained a bruised chest in New York's 35-14 loss to the Cleveland Browns Monday night, and coach Tom Coughlin was not certain about the extent of the injury although he gave indications that the Super Bowl MVP would practice for this week's game against the San Francisco 49ers.

Buffalo traded underperforming defensive tackle John McCargo to the Indianapolis Colts in exchange for an undisclosed draft pick.

Former league MVP Shaun Alexander signed with Washington. The Redskins also cut sixth-round draft pick Durant Brooks, who ranks last in the league in punting, and replaced him with former Seattle punter Ryan Plackemeier.

Former Penn State running back Larry Johnson was charged with pushing a woman at a Kansas City nightclub in February, the third time he has been charged with assaulting a woman. He is to appear in court Dec. 3 and could face a maximum jail term of six months and a $500 fine.

Also, tight end Tony Gonzalez is staying with the Chiefs. Just minutes after the 4 p.m. trade deadline, Kansas City coach Herm Edwards said no deal had been struck for the nine-time Pro Bowler. His announcement ended 10 days of tension for the player and the fans in Kansas City, most of whom were hoping he would get what he wanted and be traded to a contender.

Winless Detroit placed quarterback Jon Kitna on injured reserve, ending his season. Kitna suffered a back injury in a loss to Chicago two weeks ago. He did not play last week against Minnesota.
