Jones left Old Trafford on crutches after the Reading cup tie following a tackle on Jobi McAnuff that was described as 'too brave' by his manager.
"It was silly tackle," he conceded. "I probably should have looked after myself a bit more. I will learn from it as an experienced head would probably not have done that. But I will learn from that.
"It is in me [playing with great enthusiasm]. I like making tackles. I like defending. Injuries are going to occur in football so I've probably just been unfortunate, especially at the start of the season.
"I was gutted [to miss the Madrid tie]. I tried everything to make the game. I was on the treatment table, having massages, in the pool and in the gym. But it was just too soon for me and I missed it."
