Gore (knee) is out for the rest of Saturday's preseason game against the Panthers.
The undrafted rookie was having himself a day before leaving late in the game, carrying the ball 18 times for 101 yards and a touchdown before exiting. Gore is fighting for a roster spot on a thin running back depth chart behind starter James Cook. The son of longtime NFL back Frank Gore recorded 4,022 yards and 26 touchdowns during a four-year college career at Southern Miss. Making matters worse for the Bills, fellow running back Darrynton Evans suffered a hamstring injury prior to Gore's injury and also had to leave the contest.
