Watford boss Malky Mackay is set to name an unchanged side for the visit of Bristol City.
Goalkeeper Scott Loach was at fault for Reading's equaliser in the 1-1 draw at the Madejski at the weekend but it was a rare error and the England Under-21 international will keep his place.
Teenage right-back Adam Thompson made his fist start at Reading and will keep his place as Lloyd Doyley remains sidelined with the hamstring injury which has interrupted his season.
Winger Will Buckley is out with an ankle injury while striker Marvin Sordell has now fully recovered from his recent foot injury.
On-loan Aston Villa striker Andreas Weimann scored on Saturday though and will again partner Danny Graham up front.
Youngster Michael Bryan is still missing with an ankle injury and completes the injury list for the Hornets.
Bristol City will be without Jamie McAllister.
Scans have revealed the left-back suffered a fractured rib during the defeat to Leicester. McAllister was forced off after 64 minutes at the Walkers Stadium on Friday night following a heavy challenge that also left him with a calf injury.
The Scot`s absence aside, boss Keith Millen will pick from an otherwise unchanged squad.
Lewin Nyatanga and Damion Stewart will compete to replace McAllister, while midfielder Lee Johnson and striker Brett Pitman will also hope for recalls.
Jamal Campbell-Ryce made his return from a hamstring injury as a second-half substitute against the Foxes and could be pushing for a start after suffering no ill effects.
Last season`s leading scorer Nicky Maynard will continue to be eased back into competitive action as a substitute.
