Brandt: Proving ground in the AFC

Gil Brandt identifies two players -- one offensive and one defensive -- with something to prove on each AFC team. **More ...**

Mariani's season likely came to an end Thursday, when the Tennessee Titans wide receiver broke his leg during a first-quarter punt return against the Arizona Cardinals.

The team confirmed the extent of the injury minutes after he was fitted with an air cast and carted off LP Field. Replays showed Mariani's leg snap above his ankle in the area of his calf.

Mariani's loss leaves a major void for the Titans. A 2011 Pro Bowl selection, Mariani has established himself as one of football's top return men. It's likely Darius Reynaud -- who had been on the roster bubble -- will take Mariani's place on special teams.

Last season, the Titans ranked fifth in the NFL, averaging 26 yards per kickoff return. Mariani returned every kickoff for the Titans and had 46 of their 47 punt returns.
