Saracens have confirmed they have agreed a new short-term deal to play at least 10 matches at Vicarage Road next season.
The English Premiership side and Watford Football Club have agreed the new contract while Saracens continue negotiations to build a new purpose built ground at Copthall Stadium.
"The club is happy to welcome Saracens back to our stadium next season," said Watford owner Laurence Bassini.
"They approached us to see if we could take into account their current situation with regard to their ongoing Copthall Stadium negotiations.
"Given the long-standing relationship between Watford and Saracens, it is only right that we considered their request."
