--Washington Redskins linebacker London Fletcher underwent surgery Wednesday morning on his left ankle and has scheduled elbow surgery for later this month.

Fletcher, 37, shrugged off retirement talk after 15 NFL years and said he plans to return next season.

"Surgery is the first step towards prepping for next season," Fletcher told CBS DC.

Fletcher led the Redskins with 139 tackles last season and had five interceptions and three sacks from his middle linebacker spot.

In front office news, the Redskins named former San Diego Chargers general manager A.J. Smith as a senior executive.

Smith was fired after the 2012 season by the Chargers. He spent 14 seasons with the Chargers as assistant general manager and director of pro personnel (2001-02) and executive vice president and general manager (2003-12). His 95 wins as GM are a Chargers record.

Under Smith's guidance, the Chargers won five AFC West titles and 95 regular-season games, the fifth-most victories in the the AFC during his run as general manager.

--The Buffalo Bills announced they tendered a qualifying offer to tight end Dorin Dickerson.

The 24-year-old Dickerson appeared in 11 games with Buffalo in 2012, catching nine passes for 117 yards.

The 6-foot-1, 226-pound Dickerson played just 97 snaps last year. But his role could expand with fullback Corey McIntyre prepared to test the free-agent market and tight end Scott Chandler still recovering from an ACL injury.

Meanwhile, veteran linebacker Bryan Scott tweeted that he has re-signed with the Buffalo Bills.

By signing a one-year contract with the Bills, Scott passed up an opportunity to become an unrestricted free agent next week and test the open market.

Scott, 31, finished the 2012 season with 66 tackles, four interceptions and two fumble recoveries.

--Linebacker DeAndre Levy reached agreement on a new three-year contract with the Detroit Lions, according to multiple reports.

Terms of the deal were not available. Levy, 25, was set to become an unrestricted free agent next week.

A four-year starter, Levy was the Lions' third-leading tackler last season with 83. He played middle linebacker his first two years in Detroit and then moved to the outside.

--The Denver Broncos are asking pass-rushing specialist Elvis Dumervil to restructure his contract, according to multiple reports.

Dumervil is due to receive $12 million next season and the Broncos want to renegotiate because their payroll includes quarterback's Peyton Manning $20 million salary and defensive back Champ Bailey's 10 million salary.

If Dumervil and the Broncos fail to reach a deal at a more manageable cap figure, Denver might release him and seek the likes of Dwight Freeney in the free-agent market, NFL.com reported.
