Gareth Bale has labelled Charlie Adam "a coward" after being left on crutches by a tackle from the Liverpool midfielder.
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.
In quotes reported by several national newspapers, Bale said: "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."
Bale and Adam have history following the latter's challenge when he was playing for Blackpool in 2011.
Bale added: "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."
