Fabini accepted a football scholarship from the University of Cincinnati, where he was a four-year starter at left tackle and an All-Conference USA selection. In his junior season, he contributed to the school's first bowl-game invitation in 47 years.[2] He played in 44 career games and made 43 starts.
In 2009, he was inducted into the University of Cincinnati Athletics Hall of Fame.[3]
In 1999, he started 9 games (8 at right tackle and one at left tackle) and was lost for the season after suffering a torn anterior cruciate ligament, in the ninth game against the New England Patriots. In 2000, he became the starter at left tackle and helped the offensive line tie a league low 20 sacks allowed on the season. He remained in that role and didn't miss a game for the next 4 seasons.
In 2005, he was moved to right tackle after struggling on the left side. He started 9 games before he was placed on the injured reserve list with a torn chest muscle.[5] On February 22, he was released for salary cap reasons.
Dallas Cowboys
On March 18, 2006, he was signed as a free agent by the Dallas Cowboys, reuniting him with his former Jets head coach Bill Parcells.[6] Although he had the inside track for the starting right tackle job, he was passed on the depth chart by Marc Colombo and relegated to special teams duties. He was released on March 10, 2007.
He signed a second contract with the Redskins exactly one year later on March 26, 2008. He appeared in 7 games with 2 starts. He was not re-signed after the season.[9]
