Tom Zbikowski

Zbikowski returned to the ring again in 2016 and won all three of his fights that year. His last fight was on October 17, 2017, when he defeated a boxer named Martez Williamson who was ranked 639th in the world at the time, and whose won-lost record was 3-20 after the bout.

In 2015, Zbikowski completed fire academy training and joined the Chicago Fire Department.

On March 23, 2013, Zbikowski was signed by the Chicago Bears to a one-year deal worth $715,000, but was released on August 25 during training camp.

On September 10, 2013, Zbikowski was suspended by the National Football League for four games for violating the league's performance-enhancing drug policy. He later stated that the banned substance was a diuretic he took to lose weight. In November 2013, he told David Haugh of the Baltimore Sun: "I don't want that label of a guy who took a PED because as much as I'm a hustler, I don't like cheating, I never even thought about that. I don't take protein shakes. I drink coffee, green tea and eat food. That's what I've done my whole life.

Zbikowski signed with the Indianapolis Colts on March 16, 2012. He was the Colts' regular starting strong safety until he was injured during the 12th game of the season, missing the rest of the regular season. He did return for a Wild Card playoff game. The Colts lost that game 24-9 to Zbikowski's old team, the Baltimore Ravens. Indianapolis released him on March 15, 2013.

On March 12, 2011, Zbikowski returned to the ring for the first time since 2007, taking on 1-2 35-year-old Richard Bryant in Las Vegas, amidst ongoing NFL labor contract discord. Zbikowski won by TKO after 1 minute 45 seconds in the first round of the scheduled four-round fight.

After that, he trained under the instruction of his new trainer Emanuel Steward, an inductee both of the International Boxing Hall of Fame and the World Boxing Hall of Fame, and won via a unanimous decision at the Boardwalk Hall in Atlantic City, New Jersey on March 26, 2011 to extend his winning streak to three in a row.

He extended his win streak to 4-0 in a first-round knock out against Blake Warner at the Winstar Casino in Thackerville, Okla. on April 23, 2011. After testing positive for a substance in marijuana, he was suspended. After taking a second test, his suspension was lifted. Bob Arum said, "I think that the commission did the right thing by lifting the suspension... The tests that were taken were very unreliable. Now Tommy has taken a proper test, and as a result, you know that he's clean. So they did the right thing."

Zbikowski was selected with the 86th overall pick in the third round of the 2008 NFL Draft by the Baltimore Ravens. He made the team and played four seasons for Baltimore as a defensive back and kick returner. He appeared in 56 games for the Ravens, including 14 starts as a safety. He made his professional debut on September 7 against the Cincinnati Bengals, posting his first career tackle on special teams during a 17-10 win. He had two interceptions in 2009, and helped as a returner. He declared free agency after the 2011 season.

Zbikowski returned to Notre Dame for his fifth year in 2007, recording a career-high 80 total tackles with a pair of interceptions and fumble recoveries. He continued to shine as a return man, racking up 234 return yards on punts. He graduated in May with degrees in sociology and computer applications.

Zbikowski boxed a three-round exhibition fight against Ryan St. Germain on March 2, 2007 at the Century Center in South Bend, Indiana. After the 2008 NFL season he decided to put his boxing career on hold to focus on football.

He served as 2006 team captain alongside Brady Quinn and Travis Thomas and was selected to the second-team All-American squad by the Walter Camp Football Foundation after helping the Irish earn a bid in the Sugar Bowl. Zbikowski was also named a third-team All-American by the Associated Press and was a semi-finalist for the Jim Thorpe Award, presented annually to the nation's best defensive back. He ended the year with 79 tackles, recovered a fumble for a touchdown against Penn State, and recorded his third career punt return touchdown with 52-yard return against North Carolina.

Zbikowski has sporadically pursued a career as a professional boxer since 2006, mostly in the cruiserweight division. He has won all 8 of his official bouts, 5 by knockout, all against little-known opponents.

On June 10, 2006, while still in college, Zbikowski made his professional boxing debut at Madison Square Garden in New York City, beating his opponent, Robert Bell of Akron, Ohio, by TKO within 49.0 seconds of the first round. The fight was compliant with NCAA guidelines. Bell, who is an Ohio State fan, wore an Ohio State football jersey into the ring.

Zbikowski played college football at Notre Dame. He made his debut as a sophomore in 2004, appearing in all 12 games and finished fourth best on the team with 70 total tackles (37 solo, 33 assisted) and two forced fumbles. He was named Walter Camp Defensive Player of the Week on Sept. 19 following his performance at Michigan State as he had a team-high nine tackles, forced a fumble and returned it for a 75-yard TD and recorded his first career interception.
