Dr. Ruairi Hanley sees lots of sporting injuries in his job.
But of all the contact sports that are out there, he believes that Mixed Martial Arts is too dangerous, and says that if he ran the country he would probably ban it.
"I'm not anti-contact sports," he explains.
"I think amateur boxing does wonderful things for young men and women in communities, and I'm happy to support that. I would regard it as just as safe as rugby."
But when it comes to MMA, he feels the "level and intensity of the violence" is too much and describes it as "a much more savage sport."
As things stand, Ruairi says that "all we can do is recognise the dangers and say to some players, 'you have to stop now before you do yourself some serious harm.'"
