The Buffalo Bills have begun releasing players from their roster in an effort to pare down to 53 players, and we're going to use this thread to keep you updated on all of the roster moves - reported and confirmed alike - throughout the day. Here we go:

QB Matt Leinart

He had a short audition with the team last night and squandered it, throwing two picks and getting pulled early. Leinart tweeted a thanks to the Bills organization earlier this morning, prompting stories like this, but that tweet has since been deleted. Still, it's a sign of the obvious: Leinart's career with the Bills will have lasted less than a week.

TE Dorin Dickerson

A reserve tight end that struggled with minor injuries throughout the summer, Dickerson appears to have tweeted the news of his release himself:

Just want to say thank you to the #billsmafia you guys have been great. Love you all — Dorin Dickerson (@scorindorin) August 30, 2013

OT Zebrie Sanders

To the surprise of no one, the Bills have released their 2012 fifth-round pick, according to Ian Rapoport of NFL.com. The writing was on the wall for the second-year tackle when he played just 12 snaps on offense through the team's first three preseason games. He is eligible for the practice squad.

OLB Kourtnei Brown

Brown created a bit of buzz early in camp with some good play, but an injury robbed him of a large chunk of preseason action. His agency reported the release (see below), but the talented pass rusher does have practice squad eligibility.

LB Bryan Scott

A teammate appears to have let the cat out of the bag on Scott, the 32-year-old veteran linebacker spotted taking snaps late in Thursday night's preseason loss to Detroit. Scott has been with the Bills since 2007.

LB Keith Pough

The undrafted free agent linebacker is another that struggled with minor injuries throughout the summer; he is eligible for the team's practice squad.

Everything happens for a reason I'm grateful for the opportunity. Thank you for everything Buffalo. Don't need to be bitter just get better! — Keith Pough™ (@ITsKPough13) August 30, 2013

CB Crezdon Butler

This cut is something of a surprise given the Bills' lack of cornerback depth at the moment, but Butler is out nonetheless, according to Mike Florio of ProFootballTalk.com. Butler started and played the entire game last night against Detroit, and along with every other Bills corner on the field, he struggled. Butler is not eligible for the team's practice squad.

After a rough outing on Thursday night against Detroit, in which Heath was repeatedly targeted by the opposing offense, it appears that Heath is out in Buffalo. A teammate let the cat out of the bag on his Instagram feed.
