PHILADELPHIA (AP) _ Brian Mitchell, the NFL's career leader in combined kickoff and punt return yardage, agreed to a two-year contract with the Philadelphia Eagles.

He was cut by Washington last week after 10 seasons with the Redskins.

``I have something to prove,'' Mitchell said Friday. ``I feel like I'm in the best shape of my life.''

Terms of his new deal were not announced.

Mitchell is expected to be the primary punt return and kick return man for the Eagles, and the team's third-down back.

He is the fourth unrestricted free agent the Eagles have signed since February, following offensive tackle Jon Runyan, linebacker Carlos Emmons and fullback Stanley Pritchett.

Mitchell averaged 8.3 yards per punt return and 20.8 yards per kickoff return last season, subpar numbers for him. He also caught 31 passes.

He was one of the premier return men in the NFL in the 1990s, becoming just the third played to lead the league in combined net yards in three straight seasons, 1994-96 _ Jim Brown (1958-61) and Gale Sayers (1965-67) are the others.

Mitchell was named to the Pro Bowl after the 1995 season.
