It is the second time Bale has been hurt by an Adam challenge, the latest coming during the goalless draw between the Reds and Spurs in Baltimore.
The previous incident, in May 2011, saw Bale suffer ankle ligament damage which meant the Wales international was out for three months.
Bale: "He's a bit of a coward. What he did was over the top. Some people are like that and it's just wrong.
"It's flattering when players try to take you out in a game but, when it threatens your career, it becomes more serious than that.
"There are pictures on the internet of what he did before when he snapped all my ankle ligaments. I was out for three months that time. He's come for me twice now - and he's got me twice.
"When someone makes a very bad tackle on you, you expect an apology. I've had no apology. And I'm not going to accept his apology."
'Over the top'? Well Bale could have been OTT with his comments because the Welsh international is in contention to feature for Tottenham Hotspur against New York Red Bulls tonight.
It was feared he could miss the start of the Premier League campaign.
However, it has now been confirmed that he has not suffered a serious problem, with the Welshman even able to do a little light jogging before Tuesday night's clash in New York.
