Atletico Madrid defender Juanfran is set to miss both legs of the club's Europa League semi-final tie with Arsenal because of a hamstring injury.
The right back was substituted in the 65th minute of Atletico's 0-0 home draw with Real Betis in La Liga on Sunday and was replaced by Sime Vrsaljko, who will likely line up on the right of the defence against the Gunners.
'Juanfran took tests which determined that our full back suffered an injury to the hamstring in his left leg,' said Atletico in a statement on Monday.
