Titans release cornerback Chidobe Awuzie

Flippin' Wikipedia has him at three games played last season.

Pro Football Reference, though, is a more authoritative source and backs up what you wrote. Thanks for the correction.

It's not so much games missed, anyway -- it's that disc. Back injuries don't just vanish. Also, players can recover well these days from knee ligament tears ... but I worry about loss of speed afterwards, even if subtle.

Yep. I know first hand, a herniated disc is no joke. The worst pain, even shoots down all the way into your right knee to where you can barely walk depending on what vertebrae gets impacted. Never truly goes away, just subsides for awhile until you harshly aggravate it again.
