What exactly is a grade two turf toe? From Core Performance:
Grade 2: Possible popping sound when the injury occurs; tenderness, moderate swelling, bruising, and loss of motion; partial tear of the capsule and ligaments; no injury to the joint surface
The recovery time for a grade two turf toe, according to Core Performance, can be anywhere from a day to two weeks. The one issue with it is that the injury can linger if it isn't fully recovered, so it may be wise to just sit Best until the Rams game next week. Then again, it will all depend on how Best is feeling, and if he isn't experiencing much pain, I expect to see him against Green Bay on Sunday.
