Pittsburgh Steelers quarterback Justin Fields (abdomen) was limited in practice the last two days and is listed as questionable to play on Christmas Day on Wednesday versus the Kansas City Chiefs. Fields did not suit up for the Saturday loss to the division-rival Baltimore Ravens in Week 16, but he could return as Russell Wilson's backup on a short week. Even if he does, the 25-year-old signal-caller obviously shouldn't be used in any starting fantasy lineups as the clear backup in Pittsburgh....
