The Bills re-signed Gore (knee) to their practice squad Wednesday, Jordan Schultz of BleacherReport.com reports.
Gore dealt with a knee injury late in the preseason, but the undrafted rookie out of Southern Miss no longer has an injury designation. The clear top man in Buffalo's backfield is James Cook, with Ray Davis and Ty Johnson locked in for the top reserve spots. Darrynton Evans (hamstring) will also handle a depth role once back from injured reserve, so Gore lacks a clear path to activation from the practice squad, barring injuries. Still, he showed enough during the preseason to warrant a chance to continue his development.
