The left-back sealed his loan move from Fulham on Friday, with the agreement coming just hours before the Hornets' 1-1 draw against Wolves at Molineux.
Briggs was unavailable to feature in the clash and so now comes into the frame to face the Owls as Gianfranco Zola's promotion chasers aim to get back to winning ways.
Goalkeeper Manuel Almunia remains a doubt with the hamstring injury which forced him to miss out on Friday night, meaning Jonathan Bond is again on standby to start.
Zola has no fresh injury or suspension concerns for the encounter but defenders Fitz Hall (hamstring), Tommie Hoban (ankle) and Neuton (back) all continue to miss out.
