Manchester United striker Wayne Rooney has suffered a head injury during training and is doubtful for Sunday's Premier League clash with bitter rivals Liverpool, according to British media reports.
Rooney suffered a deep gash in his forehead during a collision with a team mate at the club's Carrington base on Saturday and needed stitches, the Sunday Mirror reported.
The injury could also see the 27-year-old striker miss England's upcoming crucial World Cup qualifiers against Moldova and Ukraine, the paper said.
England face Moldova at Wembley on September 6 before travelling to Kiev to play Ukraine on September 10.
