Following are some whispers we've been hearing from around the AFC South:
• ORT Jordan Black struggled mightily against the Browns in Week 11, getting beaten badly on two sacks. The Jaguars are concerned about Black's ability to protect QB David Garrard, but it doesn't appear there are any better options on the roster. The club is likely to stick with the veteran in the hope that he will pick up his play down the stretch.
• The Jaguars sent a message to RB-RS Deji Karim in Week 11 by deactivating the rookie after he fumbled on a kickoff return the previous week. However, his replacement, second-year WR Tiquan Underwood, did little to earn the trust of the coaching staff, muffing a kickoff and adding two dropped passes in the win over the Browns. Word is Karim is still the Jags' best option in the kickoff-return game.
• After getting the start in place of injured WLB Clint Session in Week Nine, veteran Tyjuan Hagler was replaced by rookie seventh-rounder Kavell Conner in Weeks 10 and 11. The way we hear it, the club is very happy with the job both 'backers have done in a tough spot, but Conner has gotten the nod because he provides a bit more quickness and athleticism, whereas Hagler has been most valuable in nickel situations.
• The way we hear it, head coach Jim Caldwell was not pleased about the multiple special-teams penalties in Week 11 that put the Colts behind the eight ball in terms of field position. In addition to affecting the other two phases of the team, injuries have taken their toll on special teams, making it difficult to achieve continuity as a unit.
• Titans QB/passing-game coach Dowell Loggains will likely be the club's play-caller while offensive coordinator Mike Heimderdinger is receiving treatment for cancer, head coach Jeff Fisher said. Loggains will lead the club's passing-game preparation, with OL coach Mike Munchak overseeing the running game. Munchak, a Hall of Fame guard, is well-known and well-respected for his work with the Tennessee offensive line. And Loggains, 30, a former quarterback at Arkansas, has impressed the Titans with his intelligence, we're told. Heimerdinger was to begin treatment on Nov. 29, one day after the Titans' Week 12 game at Houston. "It's his love, it's his passion," Fisher said of Heimerdinger's desire to continue coaching as the Titans prepared for the Texans. "He understands now what's ahead. He's got a tremendous fight ahead of him, but at least he knows what to prepare for and when to prepare for it. It speaks volumes about his commitment to this organization."
