'Ross, meanwhile, is on his seventh team since entering the league as an undrafted free agent back in 2013. The 49ers released him on June 1. He has just nine career catches but also has a 101-yard kickoff return touchdown to his credit. Ross' most notable production came during the 2014 preseason when he had 25 catches for 266 yards and four touchdowns. At the very least, Ross is available to practice, which Listenbee hasn't been during his Bills career.'
