'We could have gone home as long as there was security but instead we waited. Last night the explosions woke us up.'
Russia's invasion of Ukraine was condemned by the sporting community on Thursday, with President Vladimir Putin's country losing hosting rights for the UEFA Champions League final while Formula One drivers said it was "wrong" to race there this year.
Russia launched an all-out invasion of Ukraine by land, sea and air on Thursday, sparking immediate sporting ramifications.
UEFA has moved this year's Champions League final from St Petersburg to Paris in the wake of Russia's invasion of Ukraine, European soccer's governing body said in a statement. UEFA also said the home games of Ukrainian and Russian club and national teams competing in UEFA competitions would be played at neutral venues "until further notice".
The showcase game in European club football was set to be held at Zenit St Petersburg's stadium -- known as the Gazprom Arena after a sponsorship deal with Russia's state energy company, which also sponsors the Champions League.
German soccer club Schalke 04 have had a 15-year partnership with Gazprom but said they were removing the firm's logo from their jersey while Matthias Warnig, chief executive of Nord Stream 2 AG, vacated his position on the club's board of directors. Nord Stream 2 AG is owned by Gazprom.
The men's tennis governing body said next week's ATP Challenger event in Moscow will not take place as scheduled due to concerns over player safety and uncertainty related to international travel.
"The security of players will remain our top priority in assessing the scheduling of subsequent ATP Tour and ATP Challenger Tour events in the region. We continue to monitor the situation," the ATP said in a statement.
Athletes from a number of sports also voiced their concerns about travelling to Russia.
Four-times Formula One champion Sebastian Vettel said he will not take part in September's grand prix in Sochi, adding it was "wrong" to race in Russia. World champion Max Verstappen agreed with him.
"My own opinion is I should not go," Vettel said. "I'm sorry for the innocent people that are losing their lives, that are getting killed for stupid reasons and a very, very strange and mad leadership."
The sport's governing body said it was monitoring the situation, but said nothing about potentially moving the Russian Grand Prix.
The invasion was also condemned by the International Olympic Committee (IOC) which said the Russian government had breached the Olympic Truce currently in effect until after next month's Winter Paralympic Games.
A joint statement from the football associations of Poland, Sweden and the Czech Republic called for next month's World Cup playoffs not be played in Russia.
"The signatories to this appeal do not consider travelling to Russia and playing football matches there," the statement said.
"The military escalation that we are observing entails serious consequences and considerably lower safety for our national football teams and official delegations.
Poland are due to play in Russia on March 24 with the winners hosting either Sweden or the Czechs five days later.
EuroLeague Basketball, which has teams from several countries including Russia, said the competition would continue as scheduled unless governmental decisions prevent games from taking place.
"The 18 EuroLeague participating clubs will meet tomorrow to further analyse the course of events and take any necessary actions, if needed," it said.
Bayern Munich said their EuroLeague match against CSKA Moscow had been postponed at short notice.
World Athletics condemned the Russian invasion and said its president Sebastian Coe had contacted senior vice-president Sergey Bubka and the Ukrainian Athletics Federation to offer support.
"We continue to monitor the situation carefully, but there is no reason to believe this will affect plans for the World Athletics Race Walking Team Championships Muscat 22 or the World Athletics Indoor Championships Belgrade 22," World Athletics said.
The invasion has also impacted sporting events in Ukraine.
Soccer matches in the country's Premier League have been suspended due to the imposition of martial law, leaving Shakhtar Donetsk's Italian coach Roberto De Zerbi, his staff and 13 Brazilian players stranded.
"We could have gone home as long as there was security but instead we waited. Last night the explosions woke us up. This morning they suspended the season," De Zerbi told Italpress.
Brazilian-born Ukrainian forward Junior Moraes said they were "prisoners in Kiev" while waiting for a solution to get out of the country. "Pray for us," he said on Instagram.
