'Of course, the Ragland injury wasn't the only one for the Bills as they began their second week of camp. The left side of the offensive line — tackle Cordy Glenn and guard Richie Incognito — are both out indefinitely. Glenn suffered what is believed to be a high ankle sprain in the Bills' intrasquad scrimmage Saturday and he is now in a walking boot. He may be out the entire preseason. Incognito suffered bruised ribs during practice Monday.'
