Titans' Cody Riggs: Out for Saturday's game

Riggs won't play in Saturday's preseason game against San Diego as he continues to go through the team's concussion protocol, Terry McCormick of TitanInsider.com reports.

The 24-year-old has not been cleared to play since suffering a blow to the head during Tuesday's practice. Riggs' absence from Saturday's game could prove to all but kill his chances of making the Titans' roster week 1. Currently, Riggs finds himself buried beneath Tennessee's depth chart in the secondary.
