Everton striker Romelu Lukaku will miss Belgium's upcoming Euro 2016 qualifiers against Cyprus and Israel due to a hamstring injury, manager Marc Wilmots has confirmed.
The 21-year-old, who joined the Toffees in a €36 million deal in the summer, was withdrawn in the 67th minute of the club's 2-1 win over QPR at the weekend.
Despite Roberto Martinez attempting to play down the severity of the injury afterwards, he has now been ruled out of the international double-header, with Wilmots taking to Twitter to confirm the news on Monday.
Anderlecht midfielder Steven Defour has also been deemed unfit for the two matches.
Lukaku has been in fine form this season, scoring 18 goals in 42 appearances in all competitions, despite Everton languishing in the bottom half of the Premier League table.
The Red Devils are not without other striking options, however, with Aston Villa's Christian Benteke a candidate to replace Lukaku in the starting XI, while Michy Batshuayi and Divock Origi have also been named in the squad.
Belgium are currently fourth in their Euro 2016 qualifying group with five points from three games, behind Israel, Wales and Cyprus.
