Pittsburgh Steelers running back James Conner has been downgraded to doubtful for Sunday's game against the New England Patriots, the team announced Saturday.
Conner sprained his ankle on Dec. 2 against the Chargers.
Conner, who missed last week's loss to the Oakland Raiders, practiced on a limited basis for the first time Friday.
He has rushed for 909 yards and 12 touchdowns, the second most in the NFL this season to Todd Gurley's 15.
