Even though he’s been retired for over a year now, Peyton Manning remains as busy man, as evidenced by his visit to Texas Longhorns practice on Thursday.

Manning is fresh off a visit to his alma mater, and promptly headed to Austin to hang out with the ‘Horns:

If you weren’t aware, Texas is using cutting-edge technology to track the impact of hits to the head through a partnership with Riddell.

Responding to the increased focus on player safety in football over the last several years, the ‘Horns have installed sensors in the helmet of each player, becoming the FBS team to do so across the entire squad.

Officially, the program is known as the Riddell InSite helmet monitoring system.

Here’s a video about it with more detail:

The various sensors monitored throughout each helmet measure factors like G force and direction of hit. That info is then sent to a sensor held by trainers on the sidelines.

If the helmet takes a hard-enough hit, the trainers will take a look at the player to make sure all is well.

Just in the past three weeks of preseason camp, senior safety Jason Hall, junior running back Chris Warren III and junior center Terrell Cuney have all suffered concussions, which were all tracked through Insite.
