His absence on Wednesday could lead to a recall for Loic Remy, who is wanted by a number of Premier League clubs in the transfer window.

The striker had scored Chelsea's opener before Ruben Loftus-Cheek secured progression after the break.

Costa hobbled off with four minutes remaining in Chelsea's 2-0 FA Cup third-round win over Scunthorpe.

Diego Costa is "doubtful" for Chelsea's Premier League clash with West Brom on Wednesday, manager Guus Hiddink has confirmed.

Loftus-Cheek, meanwhile, spoke of his pride after scoring his first goal for the Blues.

The 19-year-old was making only his seven appearance of the season.

And he reserved praise for interim boss Hiddink after the match.

"(It was a) really nice moment when I got the goal. I'm really really happy with that. Just to come on and play 45 minutes was amazing," he told BT Sport.

"I'm really pleased to play for (Hiddink), he's a really nice man as well as a good manager.

"It's been different, obviously with a change of managers but we've got to get on with it and I feel we did really well."
