Ukraine coach Oleg Blokhin revealed on Monday that talisman and captain Andrei Shevchenko has only a "50-50" chance of being fit for their crucial Euro 2012 match with England on Tuesday.
Shevchenko injured his knee in Friday's 2-0 loss to France and although he trained with the squad on Monday, Blokhin said he might not be able to take his place in the starting line-up for Ukraine's final Group D game.
"After the game against France, Shevchenko had an injury to his knee and we are doing everything possible to prepare him for the game," Blokhin said during his pre-game press conference at Donetsk's Donbass Arena.
"It's very hard to say (if he will play). I'm not a sorcerer. You should ask the team doctor. We have 24 hours. I say it's 50-50.
"I can't really think about whether he will play or not. The decision will be made before dinner tomorrow (Tuesday)."
Co-hosts Ukraine must win against England to stand any chance of reaching the quarter-finals, while a draw will suffice for England.
