Bones spurs really aren't a big deal, and they wont keep him out. The "spur" is a misnomer and there is no bone particles floating around in your body. Its an abnormal growth on a bone, usually because of a bone injury in that area. It easily removed but it is painful for a few weeks until the soft tissue around the bone heals. I had one on my heal and learned a bit about it. I'd be more worried about the neck fusion thing. Peyton doesnt need money, he's won a super bowl, and hes 36. There is really nothing left to prove and someone needs to give him a reality check. He can retire now and be in the HoF in 2017.
Manning needs to retire. I have soured on the idea of him coming here.
Honestly, 3 surgeries, 4 surgeries.. whats the difference... BTW does it really matter.. Manning WILL NOT be a Miami dolphin regardless if he is healthy or not, available or not, or who wants him or not..
I believe any man's finest hour - his greatest fulfillment to all he holds dear, is that moment when he has worked his heart out in a good cause and lies exhausted on the field of battle...Victorious
Whether its 3 or 4 is not what stands out. He is again looking at more surgery to remove more bone spurs and will likely need more fusions to this neck.
Go home and enjoy your wife and children. It's hard to walk away but that time has come.
