The first full week of training camp is in the books for the Bills. Four more sessions to go before the Bills host the Washington Redskins in the preseason opener next Thursday.

Tank Carder has been turning heads out at St. John Fisher. Not a big surprise. The Bills fifth round pick has always found a way to pull through. A BMX bike national champion as a kid, Carder was seriously injured in a car accident as a seventh grader and almost died. He pulled through and went on to play college football, helping TCU win a BCS game. And now, the line backer is excelling at his first pro camp.

This is just practice. We've got our first preseason game next week and then three more after that," said Carder. "It's a long season and hopefully in the preseason game I can keep doing what I've been doing out here."

And incase you're wondering how Carder received the nickname "Tank," He was born Rickey Carder and by 18 months old he weighed in at a whopping 33 pounds.

The Bills with an afternoon practice scheduled for Friday.

The Bills announced that the team has signed free agent Zach Brown. The running back out of the University of Pittsburgh participated in the Bills Rookie Mini-Camp on a tryout basis in May.

Brown, a 5'10", 220-pound running back, rushed for 357 yards on 82 carries with five touchdowns in 11 games at Pittsburgh in 2011.

Prior to Pitt, Brown was a three-year letterman at the Wisconsin where he totaled 1,152 yards and 11 touchdowns on 240 carries in 36 games with nine starts from 2007-10.
