West Ham boss Slaven Bilic admits they'll miss Andy Carroll for the clash with Watford.
Carroll is currently sidelined with a groin problem and although he flew to Dubai with the rest of the Hammers squad for a mid-season camp he has been absent from training.
Speaking to talkSPORT, Bilic said: "He is in good form. The only thing about him is that now he is a little bit injured and he didn't train for 10 days.
"That is a big blow for us but, saying that, he is going to be back very soon."
