The Tennessee Titans recently made an interesting acquisition by claiming linebacker Zach Cunningham off of waivers. The former Houston Texan was cut for disciplinary reasons two years after signing a four-year contract extension.

Head coach Mike Vrabel was not in the mood to answer questions about the addition of Cunningham, who he spent time with when he was Houston's defensive coordinator. The Titans head coach walked off in a huff after getting fed up with reporters, who continually asked about Tennessee's addition.

Vrabel seemed to get irritated at the questions about Cunningham because he is unavailable for Tennessee's game this weekend. The media members in attendance still looked to get some answer about him. Still, it doesn't seem like something worth leaving a press conference prematurely over.

Once Cunningham does get added to the team, it's not certain that he'll fortify the Tennesee defense. The unit surrenders over 24 points per game and allows a score on 42.4% of their drives. Cunningham led the league in tackles last year but the Texans still had to make him a healthy scratch, which led to his departure.

The Titans, coming off of their bye week, are facing the Jacksonville Jaguars. They're in a tight race with the Indianapolis Colts for the top spot in the AFC South.
