UFC heavyweight Shane del Rosario was hospitalized in critical condition after suffering a heart attack Tuesday.
His management team released a statement that said the fighter collapsed at home Tuesday morning and was taken to the hospital in "full cardiac arrest." He was resuscitated in the emergency room and his heart rate and blood pressure were stabilized.
Del Rosario (11-2 MMA, 0-2 UFC) was forced out of a fight against Guto Inocente (6-2 MMA, 0-0 UFC) that had been booked for next month's UFC 168 card in Las Vegas because of a rib injury.
It's unclear whether the rib injury and Tuesday's incident are related.
Del Rosario, 30, started his combat sports career in kickboxing and muay Thai before moving to MMA in 2006. He started his career 11-0 with 10 first-round stoppages.
After going 8-0 with wins for M-1 Challenge and EliteXC, del Rosario signed with Strikeforce and stopped Lolohea Mahe and Lavar Johnson in the first round.
He was booked for a fight against Daniel Cormier, but after being in a car accident, a herniated disc kept him out of the fight. He wouldn't compete again until moving to the UFC, where he was stopped by Stipe Miocic in May 2012 and Pat Barry this past December.
Del Rosario tried to return over the summer against Dave Herman, but was forced out with an injury.
