Barnett snatches point for Wigan
Wigan came back from two goals down to salvage a 2-2 draw at home to newly-promoted Doncaster.
Theo Robinson gave Doncaster the lead with 25 minutes gone when he turned in the box and fired past Scott Carson. Chris Brown doubled their advantage with a header at the near post just before half-time.
But Shaun Maloney's curled free-kick reduced the deficit on 57 minutes before Leon Barnett smashed home an injury-time equaliser.
Billy Paynter then almost gave Doncaster all three points, but his effort in the dying seconds struck the woodwork.
