Titans downgrade DL Martin to out vs. Chiefs

NASHVILLE, Tenn. (AP) Defensive lineman Mike Martin will miss the Tennessee Titans' season opener at Kansas City on Sunday.

The Titans downgraded Martin from questionable to out Saturday.

Martin missed all preseason with an injured hamstring and had been limited all week in practice. The lineman was the Titans' third-round pick in 2012 out of Michigan, and he has four sacks in 29 games in his career.
