"Via Harry Scull Jr. of the Buffalo News, the Bills have heard nothing from right tackle Seantrel Henderson since the 2015 season ended.
Henderson, the starting right tackle in 2014 and most of 2015, missed the last five games of the season due to Crohns disease. Per Scull, Henderson had surgery a few months ago for the condition. One source told Scull that nobody knows whether Henderson will even be on the team in 2016"
Well this is great news; the right side of the line ought to be fantastic this year....
