Heatley played for the University of Wisconsin hockey team, and was drafted by the Atlanta Thrashers 2nd overall in the 2000 NHL Entry Draft.
Heatley suffered a broken jaw, a minor concussion, a bruised lung and, bruised kidney, and tears of three ligaments in his right knee; his passenger, teammate Dan Snyder, was critically injured with a skull fracture, fell into a coma, and died six days later on October 5.
Heatley was charged with vehicular homicide as a result of the crash.
Heatley was injured Saturday night after SC Bern teammate Daniel Briere hit him in the eye with the puck in the second period.
Heatley, the NHL rookie of the year in 2002, missed the first 51 games of last season while recuperating from a broken jaw and two torn knee ligaments in the car accident.
Heatley is a restricted free agent, meaning the Thrashers have his rights but his contract lapsed at the end of last season.
