Watford boss Tom Cleverley is facing up to an injury headache after Tuesday's bruising defeat at home to Preston North End.
Cleverley revealed forward Kwadwo Baah and midfielder Festy Ebosele could be out for weeks, while Imran Louza and Kevin Keben will be monitored.
He told a press conference, external that Baah had undergone a scan on his thigh on Wednesday and added: "His injury looks like it could be a fairly significant one – a good few weeks. It's a substantial tear."
Cleverley fears midfielder Eboele could be sidelined for even longer with an ankle ligament injury, which the boss likened to the injury to keeper Daniel Bachmann - who is out for about three months,
He said: "Festy is not good news either, and one that we thought might not be so serious.
