Dennis Dixon joining Buffalo Bills practice squad, per report

Buffalo Bills head coach Doug Marrone told reporters on Monday that the team would be adding a quarterback to the practice squad in the wake of promoting Thaddeus Lewis to the starting lineup. WKBW's Jeff Russo reports that Lewis' old spot on the taxi squad will be filled by Dennis Dixon.

I'm told that QB Dennis Dixon is set to sign with the #Bills practice squad and will join the team on Tues. Dixon worked out with team Sun

Dixon, 28, was one of two quarterbacks that worked out for the Bills over the weekend (the other, Pat White, no longer has practice squad eligibility). A former 2008 fifth-round draft pick of the Pittsburgh Steelers, Dixon is in his sixth season in the NFL, having spent four seasons with Pittsburgh, one with Baltimore and this year's preseason in Philadelphia with his former college head coach, Chip Kelly.

It's not often that you see a sixth-year player that's still practice squad eligible; here are the league's eligibility rules if you care to try to ascertain how that's possible (we're guessing it's because Dixon has only ever appeared in four games). Either way, if this signing goes down, Dixon will have a chance to stick if Lewis starts enough games to make him ineligible for a practice squad return after EJ Manuel is healthy.
