Thursday Injury Report: Concussion Keeps Humphries Out of Action

NASHVILLE – Adam Humphries looks no closer to returning to the lineup.

The slot receiver was a non-participant once again Thursday as the Tennessee Titans continued preparations for Sunday’s contest with the Baltimore Ravens. Humphries has not played or practiced since he sustained a concussion during the Nov. 1 loss at Cincinnati.

Over the last decade, in response to increased awareness of and concern about the long-term effects of head injuries, the NFL has enforced a return-to-play protocol for players who sustain concussions. A player is limited to rest and recovery until he meets the baseline standards established through neurological examination. Then he starts with light aerobic exercise, advances to – in order – strength training, non-contact portions of practice and then full participation.

The Titans have not offered details about Humphries’ current situation, but he has not yet advanced to the non-contact portion of practices.

It is a virtual certainty that he will not be available to play against the Ravens.

Humphries was one of two Titans wide receivers who did not participate in Thursday’s workout. The other was A.J. Brown, who regularly has sat out Thursday practices in recent weeks but has returned on Friday and has been available for games.

A third, Corey Davis, returned to full activity after having missed Wednesday’s workout for an issue not related to his health.

In all, 10 Titans players did not participate in Thursday’s workout. That was one more than on Wednesday.
