Swansea City striker Fernando Llorente is set to miss the start of the season because of the arm he fractured at the end of June while on a family holiday.
The 32-year-old was Swansea's top scorer last season with 15 goals.
The Spaniard is likely to sit out the Premier League opener at Southampton on 12 August and then the home game with Manchester United on 19 August.
"I think it is unlikely he will be involved in the first couple of games," head coach Paul Clement said.
"His return will not be long after that... it was always going to be touch and go for the start of the season.
"The most important thing is that we get the arm right. You don't want him to refracture it and then end up with Fernando needing surgery, because a six-week injury can then become a six-month injury."
Despite his current injury, Llorente has been linked with a move to Chelsea to join up with former boss Antonio Conte, who he played under at Juventus.
Swansea's other options up front include Jordan Ayew, Oli McBurnie and new signing Tammy Abraham.
"Fernando's rehabilitating individually - he has not joined the team training yet," added Clement on the Swansea website.
"But assuming all goes well, we anticipate that happening in the next 10 days."
