Leeds United striker Caleb Ekuban is facing a minimum of eight weeks on the sidelines after undergoing surgery on a broken foot bone.
Ekuban was sent for an operation last week on the injury he sustained on his league debut at Sunderland on August 19.
The striker limped from the field during the second half of a 2-0 win at the Stadium of Light with a problem suffered off the ball as Leeds mounted a counter-attack.
United took time to assess the damage but decided to commit Ekuban to surgery at the start of the international break.
The Ghanaian forward, who joined Leeds in a £500,000 move from Chievo in July, will spend the next two months recovering with the aim of being back in full first-team contention before Christmas.
His injury came on the day that United agreed to sell fellow forward and player-of-the-year Chris Wood to Burnley in a £15m deal but Leeds strengthened their attack in the last week of the transfer window by signing Pierre-Michel Lasogga, Jay-Roy Grot and Pawel Cibicki.
Kemar Roofe, meanwhile, played and scored as a lone striker in United’s recent 2-0 win over Nottingham Forest, providing head coach Thomas Christiansen with another option.
Ekuban has made just two competitive outings since moving from Italy, including a goalscoring appearance in a League Cup win over Port Vale last month.
Lasogga’s prospects of making his United debut against Burton Albion on Saturday, meanwhile, could be influenced by the imminent arrival of his first child.
The on-loan Hamburg forward’s partner is due to give birth this weekend.
