Denmark are likely to be without Martin Jorgensen for their World Cup warm-up game against Tunisia.
The Udinese striker missed training on Friday with a thigh strain.
"I was just getting the rhythm back, training was fun again and I had lots of energy, so this break comes at a very bad time," said Jorgensen.
A series of injuries has left him sidelined for much of the past few weeks.
"I'm not really worried at the moment. Today I am just happy that my injury will go away in a few days, because yesterday I was afraid I could miss out on the World Cup altogether," Jorgensen said.
