The sportsmen at highest risk are jockeys.
Most of them have multiple serious concussions over 20 or even 30 year careers from falls in races and even in trackwork.
I did a bit of searching a few years ago and it went something like Jockeys, polo players, boxers and then soccer players who head the ball frequently all ahead of the rugby codes -and american football was pretty high because they use their helmets to butt into each others heads, so they hinder more than they help.
