Cormac Murphy sensibly keeps his shot low into the wind to stretch Derry's lead - Tyrone have not got to grips with the wind yet and have two wides from Ruairi Canavan and McCurry (free).

The crowd are subdued and this game has yet to catch fire.

Maybe we were expecting too much.

Second half is underway.

It's half-time in Cavan, where pre-match favourites Donegal take a deserved lead in at the break.

Oisin Gallen and Patrick McBrearty nailed the final two points of the half. Those two forwards have combined for seven of Donegal's tally.

The early exchanges were evenly contested, but Cavan have only scored one point since the opening 10 minutes.

It's been a blustery afternoon at Celtic Park, as Mickey Harte found out on his way into the ground!

Cavan had a goal chance through James Smith, but he went for power over accuracy and fired wide.

At the other end, points from Ciaran Thompson and Oisin Gallen had pushed Donegal's lead out to three points.

The home side went 20 minutes without scoring, but Paddy Lynch has converted a free to get them back on track. Five minutes to go until half-time.

Donegal have managed Caolan McGonagle's sin bin very well, as Oisin Gallen adds his second to put them back in front.

A body language expert might say Tyrone looked the happier skipping off towards the dressing rooms at half time.

Derry led by five points at one stage with a stiff breeze at their backs, but Tyrone regrouped in the second quarter scoring four of the six points before the interval.

Derry replaced Gareth McKinless with Niall Toner in the seconds before the break.

The Glen boys combine with Glass involved before Ethan Doherty splits the posts.

We've had a scrappy 10 minutes or so but given the strength of the wind blowing towards the city goals favouring Derry, Tyrone will be relatively pleased to be in touch.

Donegal will be down to 14 men for the next 10 minutes, as Caolan McGonagle is shown a black card.

The two sides are trading scores back and forth in the early stages.

Paddy Lynch knocks over a straightforward free to put Cavan ahead, before Patrick McBrearty answers at the other end for Donegal.

Cavan led once again following a converted mark from James Smith, but Donegal have another quick response - through McBrearty again.

Niall Morgan steps up and judges the wind to perfection curling a free just inside the far post. Tyrone rookie Aidan Donaghy then taps over a point as the Red Hands try to stay in touch with the rampant hosts.

Derry know this wind is a potent weapon right now and are piling on the points. Padraig McGrogan and Ethan Doherty are the latest to score.

Oisin Gallen was absent for last week's game against Cork, but he gets the scoring up and running at Breffni Park. Including the Dr McKenna Cup he takes his tally to 3-13 for 2024.

However, Donegal's lead doesn't last long, as Padraig Faulkner replies for the hosts.

Derry motoring now with Glass and Rogers dictating terms in the middle third.

The Oak Leafers have scored two points in three minutes from Cormac Murphy and Shane McGuigan, the latter after a defensive fumble by Conall Devlin.

Ahead of throw-in, both sides have made several late changes.

For Donegal, Eoghan Bán Gallagher replaces Mark Curran, Rory O'Donnell replaces Peadar Mogan and Stephen McMenamin comes in for Ciarán Moore.

For Cavan, Gary O'Rourke comes in for goalkeeper Liam Brady, and James Smith is in at right-wing back in place of Castlerahan's Oisin Kiernan.

Ciaran Daly, fresh from his 0-3 on his league debut last week, is on target again to get the Red Hands up and running on the scoreboard.

Shane McGuigan and Niall Loughlin with early points for Derry.

Niall Morgan's kickouts aren't carrying too far into the wind and Glass is already having an influence, winning the kickout which led to Loughlin's tidy finish.

Both Donegal and Cavan got their Allianz Football League campaigns off to winning starts last week and will be hopeful of keeping their momentum going with another win today.

Under the guidance of new manager Raymond Galligan, Cavan went into last week's fixture against Kildare as underdogs, but were full value for their 0-16 to 0-12 win. Talisman Paddy Lynch carried most of the scoring load with eight points, but it was Cavan's pace and power around midfield which was decisive.

They make one change to their line-up from last week, as Ryan O'Neill replaces Oisin Brady in attack.

For Donegal, Jim McGuinness' second stint as manager got off to a great start, as they trounced Cork 1-20 to 2-6. Patrick McBrearty was in fine form with 1-6, and his goal was the icing on the cake, coming towards the end of the game.

McGuinness has made two changes to his team from their win over Cork, with Shaun Patton coming in for Gavin Mulreany in between the sticks, and sharpshooting forward Oisin Gallen coming in for Kevin McGettigan, who was taken off through injury last week.

Cavan: L Brady; O Kiernan (Denn), K Brady, J McLoughlin; O Kiernan (Castlerahan), N Carolan, P Faulkner; R Donohoe, K Clarke; C Brady, D McVeety, G Smith; P Lynch, R O'Neill, T Madden.

Donegal: S Patton; E Ban Gallagher, B McCole, D MacGiolla Bhride; R McHugh, C McGonagle, S McMenamin; C Thompson, D O Baoill; R Donnelly, O Doherty, Shane O'Donnell; P McBrearty, O Gallen, J Brennan.

After a minute's silence to mark the passing this week of Brendan Harkin, a former Tyrone chairman and Central Council delegate, we are underway at Celtic Park.

Derry have the benefit of a strong wind blowing straight down the pitch in this first half.
