LB Brandon Siler out for the season

This is a prime example of why Kansas City coach Todd Haley took it slow during training camp.

Haley spent much of training camp working on conditioning rather than hard-core football because of the extended lockout. Haley wanted to make sure his players were in shape and he wanted to avoid injuries. Haley took heat for the approach, but it made sense. The Chiefs have stayed pretty healthy. Until now.

Free agent linebacker Brandon Siler was lost for the season after tearing an Achilles tendon during a full-contact, goal-line drill on the final play of practice Tuesday. He has already undergone surgery.

Siler, who was signed from San Diego on a one-year deal, had been pushing Jovan Belcher at inside linebacker for playing time and is also a special teams ace.

He is only 25 and is an intriguing player. Now, he will have to wait a year to play and hope to get a chance somewhere to prove himself.
