IF it's a complete tear it isn't 100% impossible that he could play in the Super Bowl if we make it.
Cam Akers played RB 4.5 months after a tear. That's almost exactly the Super Bowl timeframe from yesterday.
I should also note the obvious: Cam Akers was practicing for a while before he actually played. It's not like he went from torn Achilles to right into the game as soon as it was feasible.
SO, Tre could always be practicing for a few weeks during the playoffs which would be an enormous boost for both him and the team, even if he doesn't get into the game.
Just saying that it has been done before. Every player is different, every body heals differently, and we don't know the exact injury yet. If a RB can do it and then play a major role for the Rams carrying the ball just a handful of months later it is possible.
Either way, he should be back to 100% next season for sure. It sucks now, no doubt, and you feel for the guy because he is a great human being as well as a great player.
