Alonzo Highsmith fought as a Heavyweight for four years after he retired from the NFL.
Highsmith finished his boxing career with a record of 27-1-2, 23 KOs, but according to Wikipedia three of his wins were eventually withdrawn when it was determined that Highsmith–no pun intended–was high, under the influence of marijuana.
Like Seth Mitchell after him, Highsmith’s physique was one of the most impressive in boxing.
