It was something Marcus Richards had done a thousand times before - refereeing a rugby match on a Saturday afternoon.
But, this time, it was to be a life-changing experience.
Just 10 minutes into taking charge of a game between Bridgend Athletic and Tondu at the Brewery Field, he suffered a stroke.
That was just over a year ago. What has followed has been a hellishly tough 12 months.
He is still physically impaired, struggling for balance and unable to write, while he has spent a long period off work.
But what really hurts is the knowledge he will never referee a match again.
That fateful game in Bridgend on February 29, 2020, should have been a leap year day to remember.
After 14 years of refereeing at junior, schools, youth and lower league level, he was taking charge of his first Division One game.
What happened next changed everything.
Speaking from his home in Porth, Richards takes up the story.
“I can remember it quite distinctly,” he says.
“About 10 minutes in, I was running from a ruck and, as I put my foot down, it felt like I was reaching for the floor. It was as if the ground was stepping away.
“Then about three or four minutes later, I was moving away from a scrum and I could feel my studs were dragging across the floor and making me trip up.
“I thought ‘There’s something not right here’.
“It was as if someone had given me one on the chin and I was doing all I could to stay on my feet. My knees were gone.
“So I blew up and called both captains over and explained I wasn’t feeling too good.
“Both physios came on and they were asking me if I’d had plenty of sugar, that kind of thing.
“I said I’d try and carry on, but one of the physios said ‘You’ve got to come off’.
“I said ‘No, I’m fine’, but as I did I stumbled and they grabbed me.
“They said ‘This can’t happen, we’ve got to get you off’.
“I couldn’t get my feet off the floor. They literally had to drag me into the changing room.”
Yet Richards wasn’t unduly worried at that stage.
“I had no idea of what was going on with me,” he said.
“I thought I was just feeling feint.
“There was a 70th birthday party up at Wattstown RFC that night and it was my intention to just chill out, get home and get to the party.
“But then I went to the toilet and it was like when you have had a real skinful at the end of a night and you’re leaning with your arm against the wall, while having a pee.
“I had to do that to stay up and I was saying ‘This isn’t right’.
“I remember a gentlemen from the WRU came in and said I had to get it checked out.”
So a trip to the Princess of Wales hospital followed and that’s when the seriousness of the situation became apparent.
“They checked my blood pressure and it was almost 300. It should be 140,” he said.
“As soon as they saw that, they said ‘Right, brain scan now’.
“The alarm bells rung and you could notice things going faster, people running round.
“They shot me down for a brain scan and, as soon as I had that, they said you have got a 1.3cms bleed on the side of your brain. You have had a stroke.
“I was flabbergasted.”
After nine days in hospital, Richards was discharged.
A year on, he continues to deal with the fall-out from his stroke.
“I still can’t write. It’s atrocious,” he said.
“I still can’t retain my balance on the right hand side.
“I can’t get in and out of the bath myself, I can’t lift anything for fear of dropping it, I am fatigued instantly. Then when I get fatigued, I start to slur my words.”
As a result, he has had to take time off work from his job as a service manager for a care and support company.
“I tried to go back in July, but within two months I realised I couldn’t do it, so had to go back on the sick,” he said.
“I have now gone back part-time as a support worker, but I am struggling with that as well, if I am being honest with you.”
Then there’s the realisation that his reffing days are over.
“There is no way I can referee again,” he said.
“It’s been 12 months now and I still can’t jog.
“It’s hard to deal with, because I loved it.
“I would do every game that was going. I have done well over a thousand, at all levels, plus being an AR in the Premiership a number of times.
“What I’m going to miss the most is the age grade games, the schools matches, doing kids games on a Sunday morning.
“It’s seeing a player, asking the coach ‘Who is that kid?”, to be told his name is Taulupe Faletau, Ellis Jenkins, Leon Brown, Elliott Dee, Tomos Williams, Shane Lewis-Hughes and so many more.
“That was a bigger sense of pride for me, more than getting promoted to level 3 and then to Performance level.
“They probably wouldn’t recognise me from Adam, but I remember every one of those as youngsters.”
Reflecting on the past 12 months, Richards says: “It’s been tough psychologically more than anything, knowing that everything I have worked for, both on the pitch and professionally has gone.
“My family have been incredible through all this.
“Friends and family have just been wonderful and the same goes for Paul Adams, the refs chief at the WRU.”
Richards, who will turn 50 in August, now knows he almost certainly had blood pressure issues going back some time.
“When I was playing five a side football or doing fitness tests, I wouldn’t sweat and I would be absolutely boiling hot,” he recalls.
“My face would turn beetroot red. I would have this feint feeling.
“I thought it was a lack of fitness, but it wasn’t that. It was my blood pressure shooting up so high.
“I didn’t realise it was that. I had no clue I had a history of high blood pressure.”
It’s with this in mind that Richards wants to send out a message on the back of what he has been through.
“What I would say to people is pay £20 for a home testing kit and get your blood pressure checked regularly,” he said.
“You might not know you have a problem. I didn’t.
“Everything I have been through is purely because I didn’t know how dangerous high blood pressure was.
“So please, get it checked.”
