Signed were defensive end Tim Swords (6-foot-3, 260 pounds) of East Carolina University, defensive back Paul McKinney (5-10, 170) from East Tennessee State and linebacker Mike Lemon (6-2, 225) of Maryland.

McKinney, 25, started two years at East Tennessee and played last year with the Carroll County Chargers of the Interstate semipro league.

Former Redskin defensive tackle (1970-'75) Manny Sistrunk tried out but was not signed. The Federals now have 40 under contract . . .
