According to Omar Kelly of the South Florida Sun-Sentinel, Norton was admitted to Jackson Memorial Hospital in Miami, Florida, in critical condition but is expected to survive.
The 22-year-old Norton is a Jacksonville, Florida, native who played his college football at Miami. In three seasons with the Hurricanes, Norton registered 84 tackles, 18 tackles for loss and five sacks.
Norton was selected by the Carolina Panthers with the No. 242 overall pick in the seventh round of the 2018 NFL draft. After spending most of the 2018 season on Carolina's practice squad, the Dolphins claimed Norton in December.
He was poised to compete for a spot in Miami's defensive tackle rotation behind presumptive starters Davon Godchaux and 2019 first-round pick Christian Wilkins.
