CHICAGO — A plane carrying Miami Heat basketball players made an emergency landing early Sunday in Chicago after a mechanic on board became ill, team spokesman Tim Donovan said.

The plane safely landed early Sunday at O'Hare International Airport after the man went into a diabetic coma. The teams' trainers treated the man while the plane was in the air and he was taken to a local hospital after the landing.

"He's OK now," Donovan said.

Heat guard Dwayne Wade wrote on Twitter about the surprise landing.

"Hey everyone pray for our pilot," Wade wrote. "... He went into a Coma. God bless this man and his family."

Donovan said the man was in the cockpit when he became ill.

The team was returning to Miami after beating the Minnesota Timberwolves 97-84 on Saturday night.
