Bale has been ruled out of his country's Euro 2012 qualifier against England with a hamstring problem which Wales manager Gary Speed claims was present when he arrived for training.
However, Redknapp has rejected that version of events and insists the 21-year-old was fit for action when he linked up with Wales.
He told the Daily Mail: "I wouldn't have let him go if he had an injury.
"Gareth played for 90 minutes against West Ham on Saturday and they tell me the figures from that game show he covered more ground than he's ever done before.
"There was no sign of a hamstring injury. He's not come in after the game and said his hamstrings were tight. When he left on Saturday, off he went and he certainly wasn't injured. Now he's got a hamstring (injury). He must've done it with Wales. I'm not blaming anyone. It's no-one's fault."
