Ben Arfa is stretchered off after the tackle by De Jong
Newcastle midfielder Hatem Ben Arfa has undergone a successful operation to repair his broken tibia and fibula.
Ben Arfa, 23, suffered the injury after a strong challenge from Nigel De Jong during Sunday's 2-1 defeat at Manchester City.
Newcastle manager Chris Hughton said: "I am delighted to hear that the operation was a success.
"Now it's just a case of nursing him back to fitness. I am sure he will make a full and speedy recovery."
Ben Arfa went down from De Jong's challenge after just four minutes of the match, before being stretchered off and taken to hospital.
The France international, on loan from Marseille, was playing in only his fourth Magpies game.
In a statement on Monday afternoon, Hughton, who previously said it was an unnecessary challenge, added: "After playing only a handful of games for us, scoring a cracking goal at Everton and doing frantically well, it's a cruel and devastating blow for Hatem, and for the club as a whole.
"All of the lads are devastated for him as well. I know many of them have already been in touch with him to check he's doing OK, and that's great.
"To get injured at any time is bad enough, but to suffer such an horrendous injury as a double leg break is sickening for the lad.
"Everyone connected with the club sends Hatem their best wishes for a speedy recovery. At this stage no time limit has been put on his expected return date."
De Jong, who was not booked for the tackle, has been
dropped from the Netherlands squad
for the forthcoming internationals against Moldova and Sweden with national coach Bert van Marwijk saying he would speak to the midfielder about some of his challenges.
