VINE: NFL player tears ACL… while celebrating a sack

As embarrassing injuries go, this is right among the worst of them.

Chicago Bears' defensive end Lamarr Houston is out for the season after tearing his ACL celebrating a sack against the New England Patriots. What's worse?  The fact that the Bears were 25 points down at the time. Houston broke free and stifled Tom Brady with an admittedly fine sack but the ensuing celebration saw him buckle to the ground and clutch his knee. And the city of Chicago were offering no sympathy to the man who has just signed a new $35 million-a-year contract when this hilarious but harsh billboard was erected on Monday.
