STANFORD, Calif. (AP) Stanford coach David Shaw said running back Christian McCaffrey is feeling better and is hopeful that the 2015 Heisman Trophy finalist will be back in the lineup against Colorado on Saturday.

McCaffrey has been sidelined since suffering an undisclosed injury in the first half against Washington State on Oct. 8. He did not play in last week's win against Notre Dame and the Cardinal (4-2, 2-2 Pac-12) are continuing to take a cautious approach with him.

Shaw told reporters that McCaffrey was scheduled to do some on-field work Tuesday. He could be cleared to join practice on Wednesday.

McCaffrey leads Stanford with 520 rushing yards and three touchdowns this year.
