Washington Redskins wide receiver David Patten is likely to undergo arthroscopic surgery on his knee today, with no estimate on his return at this point. Patten has experienced irritation in the knee the last few weeks, and has not practiced this week.

Patten, signed in the offseason as a free agent after spending four years with New England, visited a specialist in Boston, where the surgery would be performed.

Bubba Tyer, the team's director of sports medicine, said Patten had surgery to repair a meniscus problem two years ago, and the area has flared up again, almost certainly requiring surgery today. The surgeon who performed the initial procedure would do so again, and the timetable for a return would not be known until the doctors get a clear look inside the knee. "It could be two weeks," Tyer said, "or it could be longer."

Patten, 31, who starts alongside Santana Moss, was signed from New England in the offseason to add speed and diversity to the passing game, but he has not made an impact aside from drawing a key pass interference penalty in a victory over Philadelphia. Patten is third on the team with 22 catches, with only 217 yards and no touchdowns.

Taylor Jacobs is likely to start in Patten's spot, Coach Joe Gibbs said, and the team could activate a player from the practice squad, with just three healthy wideouts on the active roster, and James Thrash handling return responsibilities and heavy special-teams duties. The Redskins also worked out receiver Jimmy Farris yesterday, who was with them in the preseason.

Jacobs was hurt again for much of training camp and has been the fourth receiver all season. The 44th overall pick in 2003, Jacobs has ample speed but only two catches for 26 yards.

Dollar, Dollar Bill, Y'All

If it's Thursday, it must be time for running back Clinton Portis to don another costume for his news conference. This time, calling himself "Dollar Bill," he wore a purple wig, key-lime-colored suit with purple and black leopard-print cuffs, oodles of faux bling-bling, an abundance of fake black chest hair and glasses that spelled "COOL." Portis spent the bulk of his session referring to last week's $20,000 fine from the league for uniform violations, saying he is looking to recoup those funds. His search may take him to league headquarters, it seems, with Portis/Dollar Bill looking to align himself with some heavy hitters in his quest for justice. "There's a guy named Gene I need to talk to," he said, a reference to Gene Upshaw, the president of the NFL Players Association. . . . Running back Ladell Betts (knee, questionable) did not practice. Rock Cartwright is expected to handle his return and back-up running back duties Sunday. . . . Defensive linemen Joe Salave'a (foot) and Phillip Daniels (ankle) returned to practice after resting Wednesday and are expected to play Sunday. . . . Portis's charitable foundation will donate Thanksgiving meals to 200 families tomorrow. Portis, Moss, Betts and Cartwright will serve the meals at the YMCA Calomiris Program Center in Northeast.

A Gathering of Moss

Pro Bowl wide receiver Randy Moss drew the ire of many during his last trip to FedEx Field, heading to the locker room before the end of Washington's 21-18 victory over Minnesota in the final game of the 2004 regular season. Moss, traded to the Raiders in the offseason, caught five passes that day for 66 yards and one touchdown, despite lining up on occasion against undrafted free agents Garnell Wilds and Rufus Brown, both of whom were released by the Redskins this preseason.
