Deion Sanders -- The Honey Badger Will Rise Again ... I'm Praying For It

Here's a reason for Tyrann Mathieu to smile today ... one of the greatest athletes of ALL TIME says he's praying for the injured NFL star and believes Honey Badger will return BETTER THAN EVER!

Deion Sanders made a "get well" video for the injured AZ Cardinals defensive back -- who will miss the rest of the season after tearing his ACL this weekend while beating down the Eagles.

It's heartfelt, it's sincere and it's coming from Prime Time which means ... it's awesome.
