Cincinnati's A.J. Green is one of the finest rookies of the 2011 NFL Draft class, and already had a touchdown in the Bengals' Week 10 match-up with the Steelers when he was sent on an end-around late in the first half. That turned out to be a bad decision by Bengals offensive coordinator Jay Gruden, because Green came up limping and left the game with some sort of injury.

Green had a 36-yard touchdown catch in the first quarter of the AFC North clash, his sixth score of the season, and appears headed to a 1,000-yard season that should make him one of the best candidates for Rookie of the Year honors. But an injury could certainly disrupt that march to recognition — and, what's more, it could screw up Cincinnati's surprising season. The Bengals have relied on their rookie connection of Andy Dalton and Green all year, but Green being hurt would leave the Cincinnati receiving corps perilously thin.
