In general, the number of tackles a professional athlete can accumulate at a single venue depends on various factors such as the venue's capacity, the sport being played, the athlete's performance metrics,Serie A Stadium and the intensity of the match. For example, a professional football (soccer) player typically doesn't accumulate tens of tackles in a single game or match, as they are expected to intersperse their playing time with rest and recovery.
