Dilan Markanday fires in a low, teasing ball for Chesterfield but Thimothee Lo-Tutala is off his line quickly for Rovers to claim on the deck.

Doncaster win a free-kick on the left, about 35 yards out from goal. Luke Molyneux sends it into the box and there's a bit of a scramble before Liam Mandeville hacks it clear for Chesterfield.

Some real zip about this contest now.

I was just about to say this game hadn't really got going about five minutes ago.

Well, football always has a way of proving you wrong, doesn't it?

This game really came to live this evening and who would have thought that would have been the case after the first half we saw.

What a win for Shrewsbury in the end.

Chesterfield's leading goalscorer Lee Bonis bends one from the edge of the area and forces Doncaster keeper Thimothee Lo-Tutala into a good save.

Moments before, Rovers full-back James Maxwell was shown yellow for a heavy challenge.

There's the final whistle, it's over at last, and 10-man Shrewsbury have just done enough to see off nine-man Sutton United of the National League - what a wonderful FA Cup tie!

The Salopians did it the hard way and trailed through Kai Jennings' goal direct from a corner.

After being reduced to 10 following Josh Ruffels' red card, they dragged themselves level and forced extra time thanks to Arsenal loanee Ismeal Kabia's beautiful curler.

Sutton were also reduced to 10 men before extra time when David Ogbonna was shown a second yellow card and then went behind when John Marquis tapped the ball into an empty net following a mistake from the home side.

The U's also had Junior Eccleston sent off late on as they continued to play good football with nine men but, ultimately, it is the Salopians who will be in the hat for Monday's third round draw.

On the counter attack, Tommy McDermott hits a shot but it is kept out, somehow, between the legs of Sutton keeper Jack Sims.

That would have been the cup tie. Just over two minutes left here.

Chesterfield win a free-kick in a promising position on the left...

In it comes low and hard from Tom Naylor and it's centre-back Kyle McFadzean of all people who sneaks in unmarked but he skies the first-time effort over the bar.

Good chance for the veteran former Coventry defender.

Time's running out for Sutton, who must be shattered out there.

Even with nine men, they continue to play the ball on the ground. Fair play.

We are into five minutes of additional time at the end of extra time here.

It has been a real battle out there.

Shrewsbury are having to work so hard to keep their lead at the minute.

Shrewsbury think they have wrapped up the tie but John Marquis' header into the bottom corner is ruled out for offside.

At the other end, Lewis Simper goes so close to equalising but his left-footed effort from distance whistles past the post.

I will say it again. What a cup tie. Can the nine men find a late leveller and drag this game to penalties?

That is all about Chuks Aneke using his experience there to get the reaction out of Eccleston for that red card. Very smart from the striker.

It is all about game management now for Shrewsbury.

Plenty of decent possession for both sides in this opening 18 minutes, which has been fairly evenly contested, but just the one shot in the game so far - and what a chance it was for Doncaster.

Chesterfield shot-stopper Zach Hemming saved brilliantly from a one-on-one with Jordan Gibson after he raced through.

The League Two Spireites giving as good as they get so far against League One Rovers, though.

Straight red for Junior Eccleston! It's nine against 10 now!

It's an off the ball incident and Sutton right-back Junior Eccleston is given his marching orders for leaning with his elbow, in the eyes of the referee, on Chuks Aneke.

Replays showed that looked a little harsh and Eccleston shows his frustration by kicking a perfectly-placed water bottle on his way down the tunnel.

You wouldn't rule anything out of this one in the final 15 minutes, given the way the game has gone so far.

Sutton have been in great league form coming into this one and are putting the pressure on.

Unbelievable moment as Will Brook looks to catch a routine corner for Shrewsbury but then, on landing, drops the ball on his own goal line before receiving a whack in the head by a loose boot.

Brook has looked unconvincing from crosses coming into box since half-time of normal time.

On this occasion he gets away with it. Free-kick Shrewsbury.

Substitution for Sutton in the brief interval, Jake Taylor is withdrawn and replaced by Eduino Vaz.

Doncaster should be 1-0 up.

Jordan Gibson breaks clean through without an outfield Chesterfield blue shirt in sight.

It looks for all the world as if we're waiting for the net to ripple but Zach Hemming does brilliantly to race out of his goal and save from Gibson.
