Vorskla have claimed their Europa League tie with Arsenal may not be played on Thursday due to concerns over UEFA's decision to switch the game to Kiev.
UEFA announced on Tuesday the match was being moved to Kiev's Olimpiyskiy Stadium , which hosted the 2018 Champions League final between Real Madrid and Liverpool, because of security issues.
European football's governing body said its Emergency Panel made the decision "following the introduction of martial law into certain regions in Ukraine".
