San Francisco 49ers running back Christian McCaffrey is dealing with an ankle injury.
Head coach Kyle Shanahan told reporters on Monday the two-time All-Pro is day-to-day with a mild ankle sprain.
Shanahan also announced starting left guard Aaron Banks will sit out the regular-season finale after injuring his knee and ankle against the Las Vegas Raiders. He left Sunday's game in the second quarter and was replaced by Daniel Brunskill.
Brunskill will likely start on Sunday against the Arizona Cardinals, with Banks set to be re-evaluated next week to determine his status for the start of the playoffs.
