Yes i know of that one. However, they do not include others such as muay thai or those MMA fights. Also, most A, B and C div competitions are also left out, not to mention the Netball competitions and Thourkball compts too.
exhibition/friendly matches or similar are arranged between teams, (ie not official). these matches can be arranged by word of mouth within days, and hence it's not 100% possible to have such events on calenders. u can check with the team you're interested in shooting about their schedule.
