Lusk made his NFL debut with the Eagles on September 12, 1976, at the age of 23, in a 27–7 loss against the
Dallas Cowboys. In the third game of his career on September 27, 1976, he
fumbled the ball with 12 seconds remaining in the first half after he opted to run instead of
running out the clock. This led to the Eagles relinquishing their 10–3 lead over the
Washington Redskins, with Philadelphia ultimately losing the game in
sudden-death overtime. He played in 14 games (1 start) during his rookie season and recorded 254
rushing yards, 13
receptions, and 119 receiving yards. This custom gained him the nickname "The Praying Tailback". He scored two other touchdowns that season, to go along with 229 rushing yards, 5 receptions, and 102 receiving yards in 11 games. ==Personal life==
