Starter Todd Heap injured his right ankle in the third quarter of Sunday's 48-3 rout of the Detroit Lions, and backup L.J. Smith has missed the past two games with an ankle injury of his own. If that duo can't play Sunday against the Chicago Bears, that would leave the Ravens with Edgar Jones and converted offensive lineman Chris Chester as the team's only tight ends.Coach John Harbaugh acknowledged Monday that the uncertainty at the position is worrisome.
