Kevin Doyle's career came to an abrupt end last week.
The Colorado Rapids and Republic of Ireland strike announced his immediate retirement from the game, after suffering from repeated headaches as a result of concussions.
Doyle's plight and the topic of concussions in football was raised to Roy Keane on Tuesday ahead of the Republic of Ireland's back-to-back games against Moldova and Wales in the coming days.
Keane was sympathetic to Doyle's plight, and praised him on a successful career at international and club level, but it was the Corkman's comments about injuries and concussion in general that raised eyebrows.
It's part of the game, players picking up injuries and getting knocks. He's a centre-forward. He's going to be having a lot of challenges with centre-halves, as he'd expect. I'm sure he's knocked over a few centre-halves himself, and he's had a few knocks. That's part of the game.
There's risk involved in everything, particularly in sport. It is a physical game. I hope Kevin has picked the right time to say 'enough's enough' for him. We wish him well of course...
If you're worried about the physical side of sport and you're wary about it, then play chess!
It's part of the game. Whether it's hurling, football, American football - you see the rugby lads. It's part of the game.
When you cross that line, there is an element of risk involved. I think the players that are playing now - it wouldn't make a difference to them. When they cross that line there is an element that they might get a knock.
Do you agree or disagree with Keane's comments? Concussion is becoming an ever-prevalent occurrence in numerous sports such as rugby and American football.
In America, children under the age of ten are not allowed head the ball in training or matches, due to concussion fears. Could we see a time when heading the ball is banned from the game?
