Indianapolis Colts Siragusa was an
undrafted free agent in 1990 and was signed by the Indianapolis Colts as a defensive tackle. He played
nose tackle to draw the double teams when the
Indianapolis Colts were in a
3–4 defense or
4–3 defense. As a rookie, he appeared in 13 games and started 6 games and recorded 1 sack, 36 total tackles, and 1
fumble recovery. In the 1991 season, he started in 6 of his 13 game appearances and recorded 2 sacks, 1 fumble recovery, and 46 combined tackles. In the 1992 season, he appeared in all 16 games, starting in 12, and recorded 3 sacks and 65 combined tackles. In the 1993 season, he appeared in and started 14 games and recorded 1.5 sacks and 76 combined tackles. In the 1994 season, he appeared in and started all 16 games and recorded 5 sacks, 88 combined tackles, 2 forced fumbles, and 1 fumble recovery. In the 1995 season, he appeared in and started 14 games and recorded 2 sacks, 49 total tackles, and 1 forced fumble. Siragusa was a key part of the Colts team that narrowly lost the
1995 AFC Championship Game; after the season, he was unhappy that Colts coach
Ted Marchibroda was given a no-raise, no-extension contract offer that he rejected before leaving the team. Siragusa was open about his dislike for new coach
Lindy Infante and the team's Vice President of Football Operations
Bill Tobin. In the 1996 season, he appeared in and started 10 games and recorded 2 sacks, 45 combined tackles, and 1 fumble recovery.
Baltimore Ravens In 1997, Siragusa signed with the Baltimore Ravens, who were being coached by his former coach Ted Marchibroda (which continued until he was fired for

In the 1998 season, he appeared in and started 15 games, and recorded one forced fumble, one fumble recovery, and 41 total tackles. In the 1999 season, he appeared in and started 14 games, and recorded two forced fumbles, one fumble recovery, 3.5 sacks, and 36 total tackles. He was a part of the 2000 Baltimore Ravens defense that allowed the fewest total points in NFL history for a 16-game season. In the 2000 season, he appeared in and started 15 games, and recorded one fumble recovery and 27 total tackles. Siragusa was fined $10,000 for an illegal hit on Oakland Raiders quarterback
Rich Gannon in the 2000 AFC title game, injuring Gannon's shoulder. He helped lead the Ravens to their first
Super Bowl in franchise history in
Super Bowl XXXV where they beat the
New York Giants, 34–7. Siragusa retired following the 2001 season, where he had two sacks and 28 total tackles. He finished his career with 562 tackles (416 solo), 22 sacks, five forced fumbles, nine fumble recoveries for 12 yards, and 28 pass deflections in 170 career games. ==Post-playing career==
