Watford's head of injury prevention and rehabilitation Alberto Leon says the club are waiting on a prognosis for Danny Welbeck's ankle injury.
The striker lasted only a few minutes before being substituted during last Saturday's draw with Watford
"We are waiting on the report from one of the specialists," said Leon.
"We did a first report and it's not the best news but we are waiting for this opinion. We will decide in a few days what we are going to do with the rehab."
