The Panthers signed Blackshear to their active roster off the Bills' practice squad Wednesday, Aaron Wilson of ProFootballNetwork.com reprots.
Blackshear had a strong preseason with the Bills after being signed as an undrafted free agent out of Virginia Tech and landed a practice-squad deal with Buffalo after being waived ahead of the 53-man roster deadline. The Panthers' haven't released their official Wednesday injury report yet, but it appears their running back room is healthy, suggesting Blackshear will likely operate on special teams.
