Martin Rucker's season is over before it even started. Last week the former Mizzou tight end, who the Kansas City Chiefs signed earlier this offseason, went down with a knee injury and the three worst letters a Chiefs fans can hear were uttered: A-C-L.

Romeo Crennel is the one who initially acknowledged that Rucker could have a serious injury and the doctor's second opinion unfortunately confirmed the first opinion -- Rucker needs knee surgery.

Josh Looney of the Chiefs official site writes via Twitter that the Chiefs have decided to shut him down. Rucker will be placed on injured reserve. His season is over.

It's unfortunate that Rucker didn't get an opportunity to go to training camp in St. Joe, his hometown. With another injury, you have to wonder if Rucker will ever play again.

This opens up a roster spot on the team so be on the look out for a potential signing.
