Von Miller out with knee injury

— -- HOUSTON -- Denver Broncos linebacker Von Miller will undergo tests Monday on his left knee to determine the extent of the injury he suffered in Sunday's win over the Houston Texans and to gauge the star pass-rusher's availability for Denver's postseason run.

The evaluation on Miller will include an MRI on his knee.

"They'll have tests, that's in the medical people's hands right now," Broncos coach John Fox said following Sunday's 37-13 victory. "Anything, until we get all the tests, will be purely speculation. We'll just wait until we hear something definitive."

Miller left the game midway through the first quarter after his leg buckled as he was fighting to get off a block on a 3-yard completion from Matt Schaub to Keshawn Martin. Both Miller and defensive end Shaun Phillips were down after the play, but Phillips got up and walked off the field as Miller was helped to the sideline.

Team officials were still hoping for the best as they prepared for the return trip to Denver, but some with the team fear Miller might have at least some ACL damage and
