Jake Scott, a starting defensive back for the Redskins for three years prior to this season, was dropped yesterday by the Minnesota Vikings as NFL teams cut their rosters to the league limit of 45.

Scott, signed as a free agent in July before the start of training camp, was beaten out by veteran Paul Krause at safety. "Keeping Krause and Scott was a luxury we could not afford," said Viking Coach Bud Grant.

Scott told a reporter as he left camp, "I'm just grooving along."

Meanwhile, the Miami Dolphins waived veteran kicker Garo Yepremian and traded promising fullback Leroy Harris to the Philadelphia Eagles to a future undisclosed draft choice.

The Miami Dolphins waived veterans kicker Garo Yepremian and traded promising fullback Leroy Harris to the Philadelphia Eagles yesterday as NFL teams reduced their rosters to a league limit of 45.

Yepremian, 35, had been the Dolphin kicker for nine years and ended last season by connecting on 16 straight field goal attempts, tying a league record. He will be replaced by Uwe von Schamann, 22, a seventh round draft choice from Oklahoma.

Harris, Miami's starting fullback much of last season who gained 512 yards, was dealt to Philadelphia for an undisclosed future draft choice. He lost his starting job to veteran Larry Csonka.

Former Redskin Steve Kiner, a linebacker who Coach Bum Phillips said helped make the Oilers a winner, was waived by Houston along with three other players.

The NFL granted the San Francisco 49ers a temporary exemption for running back O. J. Simpson, who has been in Los Angeles since the Aug. 18 swimming-pool accident that claimed the life of his youngest daughter, Aaren, 2, who died on Sunday after nine days in a coma. Simpson, the second leading rusher in league history, will not count on the 45-man roster until he returns and is ready to play.
