In the pretty URL is it just one word before the name of the sport? If so you don't have to get fancy; a simple ([a-z]+) will do.
Conversely does the person's name in the pretty URL come after the name of the sport, with nothing else after that? That makes the whole thing a ### of a lot easier.
Oh, oops, you're in a config file. I'd been assuming htaccess. If it's config, then the pattern needs to start with / but this will make no difference since you won't capture it either way.
