Allen practiced with the third-team offense for the fourth straight practice Tuesday, Mark Gaughan of The Buffalo News reports.
The Bills will almost certainly start AJ McCarron or Nathan Peterman in Thursday's preseason opener against the Panthers, and it's becoming more likely the two veterans work with the starters for most of the preseason as the Bills try and determine their Week 1 signal-caller. The plan seems to be easing the promising Allen into the starting role, which might have to wait until well into his rookie season. He's a draft target in keeper leagues, but probably not in most redraft formats.
