After missing seven snaps in Week 1, right guard Andrew Tiller sat out another four in Sunday's loss to Carolina. Marcus Martin filled in, allowing a sack on one of his first plays.
After the game Chip Kelly said coaches planned on rotating players throughout the game because of the heat and humidity in Charlotte. Tiller, however, was the only starting offensive lineman to miss a play, though he returned late in the fourth quarter. The others played all 65 offensive snaps.
Tiller injured his ankle against the Rams and was on the injury report during the week. Martin's four snaps were his only action of the game; he did not play on special teams. Meanwhile, first-round pick Joshua Garnett got his first-ever NFL regular season snap on the field-goal protection team in the first quarter. He played six snaps total, all of them on special teams.
With Anthony Davis (concussion) and John Theus inactive Sunday, left guard Zane Beadles would have bumped outside to tackle if there had been an injury there.
