Manchester United defender Phil Jones has admitted that he was frightened when he learned that he had a blood clot in his calf before the start of the season.
The 23-year-old was ruled out of the start of the campaign after discovering he had the problem after talking with the club doctor about a persistent calf injury.
A scan showed that Jones had a blood clot in his calf which required immediate treatment and sidelined him for six weeks before he was given the all-clear to return to action.
He is quoted as saying by The Mirror: "It was pretty frightening at first at least until I found out the extent of the injury. And then it was just about doing the right thing, and recovering well and making sure it went.
"It happened in pre season against Barcelona and I just felt some tightness in my calf and it kept coming and didn't go away. I thought nothing of it at first. We got back to England but a couple of days before we played Tottenham in the first game of the season I felt it again.
"I just said to the doctor at United 'it's just not going away'. So we had a scan then and discovered there was a blood clot in the calf. It is what it is. You can't change that. It's not from the tackle or a stupid injury, it was just a freak incident, just a freak thing. Now I'm on a blood thinning tablet."
Jones has made seven appearances for United this season.
