Paul Walsh looks set to score the game's opening goal but Mattie Donnelly did just enough to knock him off his stride as the Tyrone defence parted.

The warning lights were flashing there.

Back underway in Castlebar and two Donegal changes with Daire O Baoill and Conor O'Donnell come in and the former opens the second half scoring.

Peter Harte is on for Tyrone at the start of the second half, replacing Michael O'Neill.

Cork's game is based on high energy. John Cleary is probably hoping they can keep that up for the entire 70, 75 minutes.

But you have to expect a response from Tyrone.

It's a great game. Two teams really going at it. Tyrone have coughed up a lot of possession and Cork capitalised on that.

This has felt more like a training session than a championship match as Donegal hit 1-11 without reply after Emmet McMahon opened the scoring for Clare.

Ryan McHugh has hit 1-2 including a goal on five minutes, seven different Donegal scorers across the first half including 0-3 from captain Patrick McBrearty.

Donegal eyes will more than likely turn to Tullamore to decide their final positioning.

Steven Sherlock converts a free and immediately Paddy Neilan blows the half-time whistle.

The Cork crowd are on their feet and making themselves heard as the Rebels make their way off the field.

It's finely balanced at the break.

You'd feel Tyrone need to take better care of the ball in the second half because Cork are making hay off turnovers and should be the happier side at this stage.

Ryan McHugh shoots over once again and brings his personal tally to 1-2 finishing off a fine team move.

Cork's memorable win over Donegal two weeks ago, coupled with the fact their hurlers are playing in the second game of this double bill in Tullamore, means there is a huge Cork crowd here and this is more like a home game for the Rebels.

Tyrone's support has been paltry all year while every Cork turnover is being cheered to the rafters.

Conn Kilpatrick is off balance but his shot is on target after being found by his Edendork team-mate Niall Morgan.

Mark Cronin replies for Cork, with the sides level for a seventh time.

Patrick McBrearty gets his second and third of the day and the championship feel is starting flow out of this game very quickly.

Clare have now not scored in 28 minutes.

Seanie O'Donnell scores from a really tight angle for a third point in-a-row from Tyrone but Brian O'Driscoll (not the rugby one) equalises for Cork.

Ryan McHugh adds to his earlier goal with a fine point from the narrowest of angles shooting amongst a sea of bodies.

Ruairi Canavan scores a superb point and breaks out a big smile.

Not to be outdone, big brother Darragh follows up with another point to draw Tyrone level.

Oisin Gallen lands a 45' and Ciaran Thompson quickly follows up with a trademark score.

Darren McCurry has the ball in the Cork net after a superb finish but referee Paddy Neilan rules it out having blown Darragh Canavan for over-carrying in the build-up.

Cork go straight down the field and punish Tyrone with Jones' third point.

A rare point by Michael O'Neill.

It was Mattie Donnelly who rode a couple of tackles to breach the Cork defence and set up the chance.

Oisin Gallen gets his first of the game and he becomes the sixth Donegal player to score, all of it from play.

Steven Sherlock shoots on sight and puts clear daylight between the teams for the first time.

Cork's strong running game is causing Tyrone real problems when they have to turn and run back to their own goal.

Chris Og Jones' searing pace beats the Tyrone defence and he splits the posts for his second point of the day,
