West Ham United coach David Moyes confirmed that Ukraine forward Andriy Yarmolenko has participated in light training, but said on Tuesday the player would decide whether to play in the FA Cup tie against Southampton on Wednesday.
The 32-year old Yarmolenko, who was given time off after Russia's invasion of Ukraine last week, did not play in West Ham's 1-0 Premier League win over Wolverhampton Wanderers on Sunday.
"Andriy Yarmolenko came back in and did a bit of light training yesterday. I had a good chat with him," Moyes told reporters on Tuesday.
"Obviously, he is really upset with the whole situation as many people are especially those from Ukraine so we will not rush him.
"I've asked him to come in today and see how he feels. If he feels fine and up to it, he'll travel with the team. If he doesn't, we'll give him some more days off."
World soccer's governing body Fifa and European counterpart Uefa on Monday suspended Russia's national teams and clubs from international football until further notice.
Moyes, whose team face Sevilla in the first leg of their Europa League last-16 tie on March 10, said he agreed with the sanctions on Russian soccer, including Uefa's decision to move the Champions League final to Paris from St Petersburg.
"It could probably have been done even quicker," he added. "Uefa have worked really hard.
"Football is such a powerful tool all round the world. Every country watches the Premier League and the Champions League. Because of that, it's really important we take action and make sure we isolate them completely.
