SANTA CLARA, Calif. — San Francisco defensive lineman Glenn Dorsey continues to believe he’ll play football this season, although it will not be Sunday against the Washington Redskins.

Dorsey, who came off the injured reserve list this week, continues to experience problems following surgery to repair a biceps tear.

“I have no doubts,” Dorsey, a former LSU standout, said Friday after being declared out, along with tackle Anthony Davis, who continues to experience post-concussion symptoms. “We’ll see how it goes. We have to work with it.”

Davis apparently sustained a concussion late in the fourth quarter. He tweeted that it occurred on the final offensive play of the 49ers’ win over the New York Giants.

Jonathan Martin is set to make his sixth start of the season at right tackle in Davis’ place.

Linebacker NaVorro Bowman, out all season following knee surgery, was scheduled to visit with his surgeon, Dr. James Andrews, with the plan of setting up his practice schedule for next week.

With defensive lineman Ian Williams also down, second-year player Quinton Dial figures to get his second NFL start against the Redskins.

Jets-Bills

FREE TICKETS FOR GAME IN DETROIT: Are you ready for some free football at Ford Field?

Fans are being offered free tickets to the NFL game between the Buffalo Bills and New York Jets on Monday night that was moved to Detroit from snow-plagued western New York.

The game was originally scheduled for Sunday at noon at Ralph Wilson Stadium in Orchard Park, New York, but the league relocated it to the Lions’ indoor stadium after a lake-effect storm dumped about 7 feet of snow on the Buffalo area since Monday.

The Lions announced Friday that their season-ticket holders and those for the Bills can use Flash Seats — a digital entry ticketing system — for general admission seats to the game Monday night.

Fans who had tickets for the game at Ralph Wilson Stadium and travel to Detroit will be admitted with their original tickets.

The Bills also announced that full refunds will be given to all original ticket holders and season ticket members, whether or not their ticket is used to enter the rescheduled game.

The public can get tickets beginning at 9 a.m. Saturday via Flash Seats at Detroitlions.com, and from 9 a.m. to 2 p.m. Sunday at Ford Field’s box office.

Falcons

WR DAVIS ACTIVATED FROM PUP LIST: In Flowery Branch, Ga., the Atlanta Falcons activated receiver Drew Davis from the physically unable to perform list.

The Falcons (4-6) announced the move Friday heading into their game against the Cleveland Browns.

Receiver Freddie Martino was waived to make room for Davis, who has 16 receptions for 216 yards and three touchdowns in 32 career games for Atlanta. He also has played a key role on special teams and will help fill the void left by Antone Smith’s season-ending injury.

Davis missed training camp and the first 10 games after foot surgery in July. He has been practicing the last two weeks and the team faced a Monday deadline to decide whether to add him to the 53-man roster.
