If he was vaccinated, yes, absolutely. If not, it's the equivalent of a player doing his hamstring during a street kickabout with his mates.
Nothing to do with that at all.
Whether he's vaccinated or not makes no difference to how it could have affected him in terms of him getting his fitness back.
I had COVID in July, 3 weeks after getting my first jab. I'm 26, so would have been in the line before 23-year-old Godfrey.
I was ill for a few days, but it took me absolutley ages to get my fitness back. I'm a keen cyclist and runner. For perspective, I cycled 110k the day before I tested positive, and 40k that day (before I knew I was positive obviously). Heart rate in the 120s/low 130s on average, averaging 28kmph.
I still, two months later, can't manage a 40k ride mate. I'm struggling to sustain power and I'm lucky if my heart rate is in the low 140s on average. I was just about back to doing them and getting my runs up when I had my second jab at the start of September and that set me back again.
I can't stress how much it can affect you long term in terms of fitness. And while I consider myself fit and healthy (Vo2 max in the top 10% for my age which ain't bad going), I'm not an athlete who is relying on their fitness and strength and power. It takes that from you - that's the biggest thing, that power and ability to recover and go again and feel just as strong. I can't describe it other than that. My mate, who is a footballer and cricketer, had no such issues with his long-standing fitness. It just affects everyone differently.
