I don’t recall seeing anything official about Salyer being injured but with him not taking a snap and Kirby bringing in a recently injured Wilson makes me wonder what’s going on there.
I do wonder why Shaffer was the first backup in but in the case of Wilson, I think that was more a matter of getting your A-Team on the field at a critical juncture of the game.
Salver was in on field goals and was a protector on punts along with Ben Cleveland.
Suggestion: Put a question mark in your header so people don't assume that Salyer is injured without any confirmation.
Shaffer has worked as the backup LG in practices while Jamaree has worked RG and RT ... my guess is he's been as impressive as JS, and Kirby was pleased with the job he did Saturday night other than the personal foul
