fortunately in most cases it's treatable and frederick found it VERY early. Would hate to see (more than likely) the best center in the NFL go down to this. I love the cowboys and consider them my 2nd team (check the name ;) ).

Health over football though.

Fortunately they have an excellent backup center and shouldn't miss it too much and should still be a great run blocking o line. 

Get better Travis!
