Professional career

In 1975, he was the fourth linebacker on the depth chart and was used on passing downs, on a team that played in Super Bowl X.

Tampa Bay Buccaneers

The Tampa Bay Buccaneers selected him from the Cowboys roster in the 1976 NFL Expansion Draft.

He returned in the eighth game to play against the Denver Broncos, but he reinjured his knee and was placed on the injured reserve list. He could never fully recover from his knee injury and was waived the next off-season after failing a physical.
