Watford boss Walter Mazzarri is awaiting the results of a scan to determine the severity of the knee injury Mauro Zarate sustained against West Ham.
The Argentine was carried from the field after receiving 10 minutes of treatment at the end of the first half of Saturday's 1-1 draw at Vicarage Road.
It was a bittersweet evening for Zarate who, having won an early penalty against his former club, required oxygen before departing on a stretcher.
Zarate looked to be already struggling with a knock when he collapsed to the ground after twisting his knee - he is expected to have a scan in London on Sunday.
"We will check it and we will probably know how serious it is tomorrow," said head coach Mazzarri.
"He was in a lot of pain, and he was in tears, but we hope it's not too bad.
"I saw he was not completely okay, after the first knock he felt something, but he kept telling me to wait.
"He wanted to stay on the pitch. So there were two occasions when he hurt his knee."
Zarate's injury was arguably the turning point for the Hornets, who found themselves on the back foot for the majority of the second period having controlled the first.
Mazzarri highlighted the impact Zarate's injury had on Watford's performance but chose to blame his side's errors for surrendering three points.
"On the performance we deserved to go ahead," he added. "But we had injuries and we are committing too many mistakes, yet even at the end we could have won the game."
