Tom Tonks will keep sending long throws into the box for Stafford Rangers. He manages to hurl it right under the crossbar and Grimsby are able to head it out for a corner.

But the set piece doesn't beat the first man. Another throw is coming though...

This Stafford Rangers team are giving Grimsby no space at all. Whenever they get on the ball they're not allowing them to get into their stride.

If you had turned up to this game without knowing who was who, you might think it was Grimsby in the black and white stripes.

Stafford Rangers certainly aren't playing like the lowest-ranked team left in the FA Cup.

A valiant display so far by the underdogs.

Stafford Rangers forward Darrhyl Mason is causing real problems for Grimsby. He skips past Cameron McJannet who is forced into taking him out.

The free-kick comes in and there's a big coming together between Grimsby goalkeeper Harvey Cartwright and Mason.

And the ref gives the foul in favour of the Mariners.

When called into action, Russell Saunders has been there for Stafford.

It was a brilliant save to deny Grimsby their only meaningful effort on goal so far, other than when they did hit the post.

Excellent stuff from him so far.

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.

This time it's Grimsby's turn to send in a long throw.

It's flicked on by Cameron McJannet and then Harvey Rodgers heads on target but there's not a lot of power on it and Russell Saunders can punch clear in the Rangers goal.

Sums up the first 35 minutes for Grimsby so far really.

Charles Vernam tries to cross from the left but loses his balance and slices it straight out of play for a goal-kick.

The corner comes to nothing for Stafford Rangers, but the eighth-tier side are more than holding their own here against League Two's Grimsby.

Grimsby are not really asserting control in the key areas of the pitch.

How is Tom Tonks managing to get these long throws into the box like this? He hurls another one in from the right for Rangers but again Grimsby clear.

The home side recycle though and win a corner.

Stafford look pretty comfortable.

Grimsby have had one or two little chances but every time the ball goes forward Grimsby look like they're struggling to deal with them.

Proper FA Cup tie. Scrapping in midfield and Remi Efunnuga goes down for Stafford Rangers, who get the decision.

The home side lump the free-kick into the area but Grimsby can eventually clear.

A lovely ball in from the right for Rangers and Harvey Rodgers has to leap to deal with it with his head for Grimsby.

Tom Tonks then sends in an absolute rocket of a long throw but the Mariners survive as Mark Shelton heads clear.

Shelton has taken a blow to the nose in the process and has had to go off to get some treatment.

Heroic stuff from the captain Andy Burns there following-up the fantastic save from Russell Saunders. What a crucial intervention that was to mop up and see the ball out.

Stafford are going to need plenty more of that if they're going to cause an upset here today.

Russell Saunders with an excellent save to deny Joe Foulkes' effort from the edge of the area.

It was bound for the bottom corner but Saunders dives low to his right to parry it away.

Josh Andrews is lurking for the rebound but Andy Burns is there to make a vital clearance.

Stafford Rangers are having to defend valiantly.

Another corner for Grimsby is sent in by Charles Vernam from the left but the referee has spotted a foul by Cameron McJannet and that's the end of that move for the visitors.

Wow, Grimsby have got away with one big time.

Stafford Rangers goalkeeper Russell Saunders with the big route one and for some reason Maldini Kacurri ducks under it and leaves it for Grimsby instead of heading it away.

Scott Bakkor races clean through in behind but is flagged offside.

Looked to be on.
