A 2011 seventh-round pick out of Richmond, Rogers struggled as a nickel cornerback for chunks of his first two years in the league, then made Doug Marrone's first Bills roster this past summer largely because of an injury to top cornerback Stephon Gilmore. Rogers started the first four games of the season at cornerback in place of Gilmore, but had been replaced in the lineup even before Gilmore's return due to a lot of things like this that happened. Rogers had been inactive for each of the last six games.
Buffalo also released Johnny Adams from the practice squad and added another cornerback, Mario Butler, to it. That leaves them with six cornerbacks on the practice field - five on the active roster (Gilmore, Leodis McKelvin, Nickell Robey, Ron Brooks and Brandon Smith), plus Butler. It's not clear whether or not the Bills will add another corner to the active roster, but it's probably not necessary, considering that the fourth corner, Brooks, has played just 24 snaps in the past five games.
The Bills don't have any scheduled practices during their bye week, so the roster spot vacated by Rogers may not be filled for a little bit.
