A Pennsylvania teenager remains hospitalized four days after he collapsed during a game. Carter Mason suffered a "severe helmet hit" during a Rochester High School football game on Oct. 4.

The student's family shared an update via a GoFundMe page that was created to help his mother pay medical bills. "After a severe helmet hit on the field, he made it to the sideline and collapsed. He has not regained consciousness and has a brain bleed," Carter's aunt Sandra Friend wrote on Saturday.

Friend later provided an encouraging update saying Mason was "breathing on his own," and doctors "removed the intubation." She also noted that medical personnel "stopped the sedation" and the teenager was "briefly opening his eyes."

High school football player was injured during a game

Carter Mason collapsed after he suffered a "severe helmet hit" during a high school football game in Pennsylvania.

Carter was reportedly wearing a Guardian Cap at the time of the hard hit. 

The protective padded caps were introduced with the goal of reducing the risk of head injuries when contact occurs between football players on any given play. The caps are designed to be able to absorb an estimated 10% of the force of a hit, according to research compiled by the NFL.
