For the second straight day, the Buffalo Bills have made a switch in undrafted free agent rookies on their roster.
On Thursday, the team announced they have signed former Fresno State defensive back Isaiah Green. Green is a 5-foot-10, 180-pound player that had 94 tackles and 14 passes defensed in 46 games with the Bulldogs.
He takes the spot of linebacker Garrick Williams on the 90-man roster.
