Former NFL coach and executive Tom Coughlin told ESPN on Thursday that be fractured four ribs and slightly punctured his lung in a bike accident last weekend in Jacksonville.

Coughlin told ESPN he also received stitches in his head and was hospitalized for a night.

Coughlin initially went home after the crash before his family convinced him to visit the emergency room at Baptist Health in Jacksonville. Doctors performed X-rays and a CT scan and told the 73-year-old that he faces a recovery period of four to six weeks.

Coughlin said he was blindsided in the accident by another bike rider who “comes out of nowhere and clips the front of my bike.”

Coughlin was fired as executive vice president of football operations for the Jacksonville Jaguars late last season after three seasons in the role.

Known for his tireless work effort and strict attention to detail, Coughlin had a 170-150 regular-season record in 20 seasons as an NFL head coach and won two Super Bowl titles with the New York Giants.

Overall, he went 102-90 from 2004-15 with New York. Earlier in his career, he was coach of the Jaguars and went 68-60 from 1995-2002.

Coughlin’s teams made nine playoff appearances and compiled a 12-7 record.
