Steelers quarterback Ben Roethlisberger practiced Thursday, but remains bothered by a sprained left ankle heading into Sunday's wild card game at Denver. Pittsburgh offensive coordinator Bruce Arians said Roethlisberger was "moving around OK, not as good as he was." Roethlisberger originally sprained the ankle in a win over Cleveland on Dec. 8 then aggravated the injury in the second half of a win over the Browns last weekend.
