Peyton Manning for 1 had the procedure, thankfully for him it was cervical not the lumbar which is much easier to recover from. Several players over recent years have had the procedure. It is not as bad as it sounds, hell Clark had not symptom but it was caught during combine medical exam. For me I had C6 and C7 fused together and fully active and no problems.
Even players with “upper-level” cervical disc herniation have a high return rate and can return to play with similar performance outcomes compared to their “lower-level” counterparts, according to the analysis by Harry T Mai of the Department of Orthopaedic surgery at the Northwestern Feinberg School of Medicine, Chicago, USA, and colleagues. The results may help guide decisions about surgery and the likelihood of returning to competition for players with these career-threatening injuries.
The researchers identified 53 NFL players who underwent surgery for a herniated disc in the cervical spine between 1979 and 2013. Forty players had confirmed data on the level of the disc injury: 15 had “upper level” cervical disc herniation while 25 had “lower level” injuries. Forty-five per cent of the players were defensive backs and linebackers.
