Greg Hartle, a middle linebacker who spent the 1977 season on the Redskins' injured-reserve list with a bad knee, yesterday signed a multiyear contract with the club.

Hartle played out his option with the Redskins in 1977, but the team submitted a qualifying offer to him that gave them the right to match any offer Hartle received from another NFL club.Hartle elected not to shop around and accepted that offer, believed to be in the $60,000 a-year range.

The Redskins also have qualifying offers to defensive tackle Bill Brundige, defensive end Will Wynn, wide receiver Charley Taylor, running back Jim Kiick and linebackers Pete Wysocki and Mike Curtis.

The club also announced the signing of two NFL veteran free agents, running back Jeff Kinney and line-backer Mike McGraw.

Kinney, 28, a five-year veteran, was the Chiefs' first-round pick out of Nebraska in 1972. He has a 3.6-yard rushing average as a professional, and will be tried at both fullback and halfback.

McGraw, 24, the Cardinals' 10th-round draft choice from Wyoming in 1975, has played only four regular season games as a professional. The Red-skins describe him as a good special-teams prospect.
