Dallas -— Ron Springs has died at age 54.
The former Dallas Cowboys and Tampa Bay Buccaneers running back, who spent the past four years in a coma after losing oxygen during a 2007 operation, died without ever regaining consciousness.
Former Cowboys teammate Everson Walls, who donated a kidney to Springs for a transplant, says the Springs family informed him that his friend died about 4:30 p.m. Thursday at Medical City Dallas hospital.
The hospital is where Springs, who played at Lafayette High School, first slipped into the coma in 2007 after undergoing surgery to remove a cyst from his forearm.
