The Minnesota Vikings reportedly have told Brett Favre to decide this week if he wants to play this year.

Coach Brad Childress imposed the deadline on the star quarterback, according to ESPN.com, which cited two unidentified sources yesterday. However, the Sirius NFL Radio network reported later that a deadline is not in place.

When Favre, 39, retired in February for the second time, he blamed a partially torn biceps tendon for his poor play late in his only season with the New York Jets. The three-time NFL MVP said his health was the main reason behind his decision.

With the Vikings interested in bringing him back for a 19th season, however, Favre reportedly has been considering a comeback contingent on the full healing of his throwing arm.

ESPN reported that Favre had arthroscopic surgery in May on his ailing right shoulder, but that it has not responded.

Pacman's return? The Dallas Cowboys said they have no plans to bring back Adam "Pacman" Jones, the cornerback whose career has been marred by off-the-field problems.

Cowboys owner Jerry Jones raised the possibility in a weekend interview with the Fort Worth Star-Telegram. Team spokesman Rich Dalrymple said yesterday the owner had told him it was not going to happen.

After serving a one-year suspension for violating the NFL's conduct policy, Jones was acquired by the Cowboys last summer. He was released in January after problems that included a fight with his team-provided bodyguard and a six-game suspension.

Jones played for the Tennessee Titans in 2005 and '06, but lately has kept busy by appearing in the reality TV show Pros vs. Joes 4: All Stars.

Playing the lottery. Washington has become a lottery team, albeit one with no ping-pong balls to worry about.

The Redskins and the Virginia Lottery yesterday unveiled a $20 scratch-off ticket featuring the team's logo, taking advantage of a new NFL rule that allows teams to sign licensing deals with state-sponsored lotteries.

The Redskins displayed their three Super Bowl trophies in a news conference setting usually reserved for big player signings.

The ticket has a top prize of $1 million, and second-chance prizes include season tickets for 20 years and a chance to travel with the team to an away game against the Dallas Cowboys.

Patriot stays away. New England nose tackle Vince Wilfork said it made "the most sense" for him to stay away from the Patriots' voluntary organized team activities while he hopes to get a contract extension.

"It's nothing personal towards the organization. It's nothing personal toward my coaches or anything like that," Wilfork, a two-time Pro Bowl player, said on WEEI radio during the team's annual charitable foundation golf tournament in Bolton, Mass.

Wilfork is entering the final year of his six-year contract worth an average of $1.5 million a season.

Deal for Rutgers star. The Seattle Seahawks agreed to terms with safety Courtney Greene, a seventh-round draft pick out of Rutgers.

Visiting the troops. NFL coaches Tom Coughlin of the New York Giants, Jeff Fisher of the Tennessee Titans, and John Harbaugh of the Baltimore Ravens will be visiting U.S. troops in the Persian Gulf region this summer.

Noteworthy. Financier William E. Mayer will be the owner of the United Football League's New York franchise.

The UFL, which will have four teams, will begin play in October.
