Add Carlton Haselrig to the list of former NFL players venturing into the world of mixed martial arts.

Haselrig, who played with Pittsburgh (1990 to 1993) and the New York Jets (1995), is set to make his MMA debut April 19 in Atlantic City, N.J. Nicknamed "Don't Blink," Haselrig will be facing fellow 265-pound fighter Shane Ott in the main event of Battle Cage Extreme IV.

Haselrig, 42, remains the only six-time NCAA champion Greco-Roman wrestler (he won three titles on both the Division I and Division II levels). Despite not having played football collegiately, Haselrig was voted to the 1992 Pro Bowl just four seasons after being a 12th-round Steelers draft choice.

But drug and alcohol problems derailed Haselrig's football career, leading to a 1995 NFL suspension while he was with the Jets. Haselrig also has gotten arrested on numerous occasions.

Johnny Morton, Michael Westbrook, Bob Sapp and Marcus Jones are other NFL players who have pursued MMA careers after leaving football. Sapp, a 1997 third-round draft pick by Chicago, has become a superstar in Japan although was knocked out last month in his U.S. MMA debut to Jan Nortje.
