Denmark midfielder Thomas Delaney is out of the World Cup after picking up a knee injury during his team's opening goalless draw with Tunisia, the country's FA announced on Wednesday.

"We'll miss him, both on and off the pitch," said coach Kasper Hjulmand in a statement.

"Our other players are ready and we have a strong squad for the coming matches."

Delaney, who plays his club football with Sevilla in Spain, will miss Denmark's remaining Group D fixtures against world champions France and Australia.
