This is a big game for Southampton teenager Will Smallbone. He is making his first senior appearance for the Saints and almost makes it a dream debut with a neat run into the box but then fires over.

Tranmere have a free-kick on the left, which is curled in towards the back post. Peter Clarke gets there first but he's stretching as he heads it into the back of a defender and wide of the right post.

Quote from the commentator:

"There is surely no way back for Tranmere now."

Ooooo, bold. Will it come back to bite him?

Gavin Whyte tries his luck with a half volley but sends it over the bar as Cardiff keep on the hunt for an equaliser. Just over 10 minutes to go until the break.

Aston Villa are just starting to get on top and are getting to grips with the Fulham's shape now but there's been a reluctance from either team to be a bit a braver and try and force the issue a little bit.

Anthony Knockaert is involved in the build-up as Cyrus Christie fires a ball in from the right.

Robert Hall has a decent effort for Oxford from outside the box but it flies wide of the right post.

Fraizer Campbell fizzes a shot just over following a rare break by Huddersfield before Joel Coleman punches away an inviting James Ward-Prowse free kick at the other end. A game of football has suddenly broken out here.

Close to the first goal at the Amex as Neal Maupay ushers Dominic Iorfa off the ball, with the defender thinking the ball was running out of play. Mendy-esque.

From a tight angle Maupay shot at goal, but the strike was saved by the legs of Cameron Dawson, who has made a couple of decent stops for the Owls today.

Anthony Knockaert has been quite lively and prominent in the opening exchanges. He looks like he wants the responsibility and wants to make something happen for the team. That's what you would like to see from a few more players out there.

Adam Caley: I love FA Cup third round weekend. All these small clubs with terrible attendances hoping for a giant-killing to earn a few more quid. Good luck tomorrow Everton

A free-kick is whipped in from the right and Ahmed El Mohamady gets a touch on it. It's not enough though, as it glances wide of the left post.

Isaac Success tries a one-two with Nathaniel Chalobah but the backheel from his teammate doesn't come off.

Too much space for Watford on the edge of the box.

Josh Murphy sums up Cardiff's attempts to find an equaliser as his shot goes out for a throw in.

So far so good for Carlisle.

Tariqe Fosu-Henry has an effort blocked for Oxford United before Fraser Kerr has to concede a corner.

Nothing comes of it.

Almost half an hour in and we've just had our first shot on or off target in a game that has yet to be sprinkled with the magic of the FA Cup. James Ward-Prowse breaks quickly down the left and slips in Che Adams but the striker scuffs a shot straight at Joel Coleman.

Nearly 60% of the play so far from a much-changed Brighton but no real chances to speak of.
