Grimsby win a free-kick and it goes into the box but eventually drops into the grateful hands of Rangers goalkeeper Russell Saunders.

Three minutes added on at the end of the first half of extra time.

Grimsby survive the Stafford Rangers corner. We may well be heading to extra time. Unless...

The cup upset might be in danger of falling apart.

Two set pieces in two minutes and all of a sudden Grimsby Town are back on level terms at eighth-tier Stafford Rangers.

The Mariners repeat the trick from their first goal as Iwan Morgan sends in the free-kick from the right and this time it's Maldini Kacurri who powers home a header from close range.

Another effort for Grimsby.

This time it's Harvey Rodgers shooting hard and low on target from a tight angle on the left but Russell Saunders is equal to it in the Rangers goal.

Joe Foulkes gets down the right flank for Grimsby and flashes low and hard across the face of goal but Rangers goalkeeper Russell Saunders is there once again to make an important claim on the deck.

Almost a leveller for Grimsby!

Iwan Morgan skips inside from the left, beats a man and then fires low and hard from the edge of the box but it just brushes the post and goes wide.

We had a few upsets on Saturday.

Seventh-tier Guiseley beat National League Sutton United 1-0 thanks to a 95th-minute penalty by Jordan Thewlis.

Meanwhile, fifth-tier Kidderminster eased past League One Doncaster 3-0.

And a special mention for National League South club Salisbury, who are through to the second round after thrashing Sholing 6-0.
