Cowboys All-Pro center Travis Frederick diagnosed with rare auto-immune disease

Travis Frederick, one of the best centers in the NFL, will likely miss significant time after receiving some bad medical news. Cowboys center Travis Frederick revealed some awful news on Wednesday, as the All-Pro lineman announced on Twitter that he had been diagnosed with an auto-immune disease called Guillain-Barre syndrome. Frederick said he has already received two treatments for his condition in the last two days and that he is optimistic because his disease had been caught at a relatively early stage, but his doctors have told him he will be out indefinitely as he continues treatment.
