Albion boss Martin Hinshelwood hopes to have an almost full squad to choose from for the vital clash at Vicarage Road.
Bobby Zamora will again partner loan signing Graham Barrett after a six-week lay-off as Hinsh sticks with the same 11 that began last Saturday's home defeat by Grimsby.
Following the return of Zamora and Kuipers, Hinsh is buoyed by the return to action of new signings Guy Butters and John Piercy, who both had good work-outs in the midweek reserves' win.
Paul Kitson has been given the all-clear from a niggling back injury, but the striker will be given a couple more weeks to regain his fitness before joining up with Zamora and Graham Barrett in attack.
Robbie Pethick (foot), Geoff Pitcher (heel) and Nathan Jones (knee) have been joined on the sidelines by rookie striker Shaun Wilkinson who is ill.
Watford boss Ray Lewington may not risk Sean Dyche and Tommy Smith who are struggling with groin injuries.
Both players missed last Saturday's win at Sheffield United and they will not figure if the club's physios say there is a doubt.
If Smith doesn't get the all-clear to play, Heidar Helguson is likely to get the nod despite missing training with a groin problem.
The 2-1 win at Bramall Lane, the Hornets' second over top six opposition, extended their unbeaten run to five games and has helped them climb to 8th in the League.
