Claim: With a Lucky loser, there were ethical issues, including the possibility of bribery, so a new policy was introduced in Grand Slam tournaments.
Evidence: In tennis, the rule for choosing a player to enter the main draw as a lucky loser is as follows: from all players eliminated in the final round of qualifying, the highest-ranked player in the ATP or WTA rankings is the first one to enter the draw, followed by the second highest-ranked player and so on (if more players withdrew before the start of the tournament). The possibility of bribery was also a concern. Shortly thereafter, a new policy was introduced in Grand Slam tournaments.
