Carlos Edwards insists Sunderland boss Roy Keane is not to blame for his current injury absence.
The winger was ruled out for four weeks after picking up a hamstring injury in last week's 2-2 draw at Birmingham City.
Keane had blamed himself for the problem after admitting he should have replaced Edwards before the injury worsened.
But the Trinidad & Tobago international has put the setback down to misfortune, although he is disappointed to be missing some big games for Sunderland.
"You can't blame anyone," Edwards told the club's official website. "He could have taken me off and then it could have happened on Saturday, you just can't tell.
"I felt okay and then I crossed the ball just before it happened. I was unbalanced, I planted my foot down awkwardly and I think it put too much strain on it, it just went.
"It's frustrating. I have not had the best run of luck with injuries.
"There is no getting away from the disappointment, but at the same time, I'm keeping positive.
"Injuries do happen and it's how you react. I will stay positive and work hard to get back, and I will give the lads 100% support.
"It's a blow to miss games against Liverpool and Manchester United, but I will not let it discourage me, I'll just get on with it."
