Richard Kahui sees himself as unlucky rather than being a victim of a position that takes lumps out of even the most robust.
But the evidence is mixed. He's heading to Japan after four shoulder reconstructions in six years. That's been enough for him to make the call to cash in while he's still able to; he fears his body won't cope with more Super Rugby beyond this year.
The damage he's suffered has been extensive. But other regular midfielders at the top level have also been taken to the physical brink.
Benson Stanley, the hard-tackling Blues midfielder who won three test caps in 2010, spent much of last year contemplating retirement after enduring a number of serious head knocks. Sam Tuitupou, comparatively tiny at 1.75m and 88kg, suffered a number of serious injuries between 2003 and 2007 before opting to head offshore while still able to command a top-dollar contract.
Tamati Ellison returned from Japan last year with severe damage in his foot and shoulder and is now out for at least six months.
