Anderson also opened Week 12 as a limited participant in practice before sitting out Sunday's 24-21 win over the Jaguars, so it would appear he's made no notable progress in his recovery from the head injury. Even if Anderson passes through the five-step protocol and gains clearance to play this weekend against the Dolphins, it's unclear if he would dress as the No. 2 quarterback behind rookie Josh Allen, as Matt Barkley may have permanently moved ahead of the veteran on the depth chart.
