I saw this mentioned within another thread and wanted to officially link confirmation. David is a DGD and I hope that his newly chosen path will bring him as much joy as he certainly brought us!
It's a shame, but I expected it. An injury like this could have left him in a wheelchair for life, and I, for one, don't think it's worth the risk to try and continue his career. Hopefully, he can start a career on the sideline with CMR in Athens.
