Some training camp updates: Brady and Thomas at practice

[DefenseRules]

I know that there was some concern about Brady yesterday. But our boy is back at work today. Hopefully Thomas can stay on the field now. Also, PFW says that Welker is back to his old self.

Mayo got into a fight with somebody today. PFW didn't elaborate.
Also this is our current 1st string OL according to PFW:
Kaczur-LT
Mankins-LG
Koppen-CTR
Yates-RG
Britt-RT

So um, what happened to O'Callaghan? Is he hurt? I thought that he had the inside track to that RT spot.
