Russian tennis star Daniil Medvedev is very much aware that he might be slapped with an indefinite ban amid the ongoing invasion of Ukraine.
Some sports have issued a blanket ban on all Russian and Belarusian athletes in response to the war.
Tennis has so far refrained from taking that step, instead forcing all players from those countries to compete under a neutral flag and make no reference to any national colours or symbols.
It means that, for now at least, the men's world number one Medvedev is able to continue competing and maintain his status as the best male tennis player around.
But the 26-year-old has himself admitted that this current state of affairs could change at any moment.
"It's always tough to talk on this subject because I want to play tennis – play in different countries," he said at a press conference ahead of the Indian Wells Masters in California.
I want to promote my sport, I want to promote what I'm doing in my country for sure, and right now the situation is that that is the only way I can play."
Asked if he thought tennis bosses might follow the example set by the Paralympics and issue a blanket ban on all Russian and Belarusian athletes, he added: "We never know – some sports made this decision, especially I would think the team sports.
"Tennis is probably one of the most individual sports we have in the world. Everyone's living in so many different places.
"There's always a possibility, but I hope not."
Meanwhile, in the women's draw at Indian Wells, the top seed is a Belarusian who is also not able to compete under her national flag.
Aryna Sabalenka is world number three, but goes into this WTA 1000 event as favourite in the absence of Australian Open quarter-finalist Barbora Krejcikova and rankings leader Ash Barty, who won the tournament in Melbourne.
Speaking about the current state of affairs, the Belarusian said: "I feel really sad and really bad about Ukrainian citizens who lost their homes in the war.
"But unfortunately it's not under my control. I just hope for peace.
"At least we can play. I do understand [why she can't play under her national flag], but it's not under our control. We also feel really sad and really bad about this situation."
