Danny Welbeck scored an injury-time equaliser as Arsenal rescued a point against Hull City at Emirates Stadium.

The Tigers went ahead early in the second half when Abel Hernandez headed home and that goal had looked to be enough to secure the three points, but Welbeck stabbed home an equaliser in injury time to salvage a share of the spoils.
