Boxer Prichard Colon remained in critical condition Sunday morning at Inova Fairfax Hospital following emergency surgery to relieve pressure from trauma to the brain, according to a statement from fight promoter Lou DiBella, with other reports indicating the Puerto Rican welterweight is breathing on his own after entering a coma.

Bothered by dizziness and vomiting, Colon was transported to the hospital shortly after his super welterweight fight with Terrel Williams on the undercard of the “Premier Boxing Champions on NBC” broadcast of the main event featuring the District’s Lamont Peterson beating Felix Diaz at EagleBank Arena in Fairfax.

Colon’s representative, Alan Obrador, posted the following message on the fighter’s official Facebook page: “I know you’re concerned about the health of Prichard. I have just spoken with his mother, and he is recovering after bleeding on the left side of the brain. We will keep you informed of any developments in this way. We ask for prayers for the speedy recovery of Prichard.”

The previously undefeated Colon, 23, was disqualified before the start of the 10th and final round.

In a curious sequence even for boxing, Colon’s corner began removing his gloves after the ninth round, apparently unaware the fight had not ended. Eventually realizing there was another round left, Colon’s corner attempted to get his gloves back on, but too much time had passed, and referee Joseph Cooper signaled for a disqualification.

Colon (16-1, 13 knockouts) was behind on the scorecards during his third fight in three months, receiving a two-point deduction in the fifth round for a low blow.

Williams then left no doubt by sending Colon down twice in the ninth round. The last knockdown came seconds before the bell, and Colon appeared woozy and disoriented.

During the fight, Colon complained to Cooper about getting hit with punches to the back of his head. At one point, Colon had to take a lengthy break in the middle of a round to compose himself. Cooper later deducted one point from Williams (15-0, 12 KOs) in Round 7 for a rabbit punch.

“Prichard’s family has requested that their privacy be respected at this time,” DiBella said. “Updates will be provided when appropriate. We ask that everyone join us in praying for Prichard and his family.”

Fellow boxers also took to social media to offer encouragement for a quick recovery.

“Boxing family please send Prayers 4 @prichardcolon Fighters put their lives on the line everytime they step in the ring Hope he gets better,” tweeted Robert Guerrero, a former world champion in three weight classes.

Colon had become one of the top prospects in the sport after a decorated amateur career that included five national championships. Known for his power, Colon entered having won third straight fights via knockout, most recently over former 140-pound champion Vivian Harris.
