Town are now the only one of the 92 Football League sides without a win after a 1-1 draw at home to Swansea on Saturday - where on-loan Portsmouth keeper Begovic made his debut.
Regular custodian Richard Wright was left out of the squad altogether at the weekend but is fit and will be hoping to at least make the bench.
Striker Pablo Counago scored against Swansea but may be rested for former Watford striker Tamas Priskin while centre-half Alex Bruce may return to the starting line-up after a groin problem.
Winger Carlos Edwards, who was left out against the Swans after playing last midweek for Trinidad and Tobago, will also be ready for a return.
But trio Ben Thatcher, Luciano Civelli and David Norris all remain sidelined with knee injuries.
Watford will check on Heidar Helguson and John Eustace ahead of the trip.
Iceland striker Helguson has been receiving intensive treatment on the calf injury he suffered on his second Hornets debut against Leicester last month and Saturday's win at Middlesbrough came just too soon for him.
Midfielder Eustace also missed out at the Riverside Stadium after going down with a sickness bug.
Skipper Jay DeMerit is ruled out again after undergoing surgery on his eye injury over the weekend. The USA defender hopes to be back within a couple of months.
Second-choice goalkeeper Richard Lee will be checked over having missed out on Saturday after jarring his knee in training, meaning 16-year-old Jonathan Bond was named on the bench.
