Matt Denis, of Seabrook, has been in critical condition at Beth Israel Deaconess Medical Center in Boston, Mass., since being airlifted to the hospital after the Thursday afternoon crash, which occurred on Lafayette Road in Seabrook.
Classmate and friend Chris Silver confirmed Monday afternoon that Denis, who wasn't wearing a helmet during the crash, had "successful" surgery.
Further updates about Denis' condition weren't available. Hospital staff didn't return calls seeking comment, and Denis' immediate family have declined comment outside of the statements made Friday during an emotional vigil for the teen.
Students are raising money for the Denis family through a variety of ways. Special bracelets are being sold for $4, and anyone interested in purchasing one can contact Silver at 205-9840.
Also, another vigil is in the works, although there was no date set as of Monday. A 3v3 basketball tournament is also planned for the near future.
