He was selected in the third round of the 1996 NFL Draft.^[1] In his career, he played for the Tampa Bay Buccaneers (1996–2001) and the New York Jets (2002–2004).

After considering retirement since the 2004 season ended, he finally decided to do so on July 15, 2005.^[2] Although he had two restaurant businesses going in South Carolina, Abrahams was searching for a post-playing occupation, and during his playing years he swore to himself that he would never become a coach. However, while on the sidelines of his oldest son’s youth football practice, a local high school coach, whose son played on the same team as Abraham’s, approached him about helping out his team. Before long, Abraham became the head coach at Gibbs High School in St. Petersburg.^[3]
