C.J. Anderson missed practice on Wednesday to have his right knee evaluated to determine how much time the Denver Broncos running back will miss.

Anderson's right knee buckled slightly during an 11-yard run on the last play of the first quarter on Monday night.

"He came in really sore [Tuesday]," Gary Kubiak said. "So we're trying to evaluate exactly where he's at right now."

"Basically we're getting a second opinion,'' Kubiak added. "We hope to know some time [Thursday] afternoon."

Anderson has 437 yards rushing this season to go with four rushing touchdowns.
