Linebacker Gary Guyton didn’t play a snap on defense, marking the third time in four weeks that he hasn’t taken the field outside of a limited role on special teams. Guyton has been a valuable fill-in for Jerod Mayo in the past, but he’s been passed on the depth chart in recent weeks by Dane Fletcher and Tracy White. If White returns to full health (abdomen), and Rob Ninkovich’s hip doesn’t limit him, Guyton might have trouble cracking the 46-man game-day roster in the playoffs.
