A Texas native and recognizable figure in the Bills Mafia, Castro became a symbol of strength in the Bills community after doctors discovered a cancerous tumor in his spine during the 2017 season, according to the Buffalo News. Bills fans started a GoFundMe page in Dec. 2017 to raise $30,000 for Castro's medical expenses. As of Tuesday, they had raised over $47,000.
