Watford have announced the signing of Fitz Hall on a one-month contract.
The defender, who has been training with the club, was let go at the end of last season - a campaign in which he made 22 appearances.
However, Gianfranco Zola has decided to bring Hall, 32, back into the first-team squad with Essaid Belkalem, Ikechi Anya and Lloyd Doyley carrying injuries.
Hall is available for tomorrow's match against Bolton Wanderers.
Watford also signed Hector Bellerin on loan from Arsenal earlier on Friday.
