First option, obviously, in AR. If he's healthy, he plays. I don't care what the OL looks like. He's a football player, he'll want to play and he should play. It's not like he'd be coming back with a sore knee/elbow that could get re-injured through stress, etc. Once the bone heals, it's healed.
To your point, yesterday's game was huge. The loss effectively takes them out of any chances for a playoff bid, barring massive folds by several teams (unlikely). So therefore, I'd go with Tolzien until AR is ready. Let him get some reps, real game action, time to read defenses and work on his game. The Packers will need a decent bckup next year and beyond. Tolzien might be the answer, but I don't want to wait for another AR injury to find out.
