West Bromwich Albion's hopes of landing Mamadou Sakho look to be over due to an injury to the former Liverpool defender.
Baggies boss Sam Allardyce had targeted the former PSG star as a potential signing to help bolster their backline as they look to avoid an instant return to the Championship.
Recently, West Brom were told that their hopes of signing the star were unlikely due to his £100k-a-week wages, but now they look doomed to fail after he picked up a knock.
Sakho picked up a thigh injury in Palace's FA Cup defeat to Wolves and according to the Athletic he is now facing an extended spell on the sidelines making a January deal incredibly unlikely.
Palace were thought to be keen on letting Sakho leave as they look to bolster their own defence and he has only made six appearances for the Eagles in all competitions this season.
That is now likely to lead West Brom to concentrate on other targets having already signed goalkeeper Andy Lonergan and winger Robert Snodgrass from West Ham.
Speaking about Sakho after his arrival at Palace three years ago, Allardyce said: "I think two people on this front, Luka (Milivojevic) and Mama have given us more defensive resilience," he said.
"We are more defensive in terms of the capabilities of looking after the opposition's attacking forces have been improved by those two players and Patrick (van Aanholt).
"We have found that we are more difficult to score against which has been one of my first aims, my first targets ever since I first came here.
"Once we began to do that we began to win football matches and three wins out of five have all come because we can keep clean sheets so the basis of our defensive unit has grown and got better and that has been a good way forward for us to get out of the trouble we are in.
"Mama has played a big part in that, as have Luka and Patrick, and the whole team as a whole are defending better."
