Hornets pair doubtful
Watford have doubts over Sebastien Bassong and Gianni Munari.
Defender Bassong missed the midweek defeat at Birmingham with a calf problem and midfielder Munari sat out due to a groin injury, and both will be assessed before kick-off.
Playmaker Almen Abdi will be missing for the sixth straight match with his shoulder injury.
Gabriele Angella remains sidelined by an ankle injury and fellow defender Gabriel Tamas is a long-term absentee with cruciate ligament damage.
Bartosz Bialkowski will continue in goal for Ipswich as he deputises for Dean Gerken.
Gerken injured his groin in the warm up to Saturday's 2-0 win at Blackpool, meaning Bialkowski stepped in.
Luke Hyam is suspended after collecting his fifth booking of the season in Tuesday's 2-1 win over Wolves.
Ipswich would go above Watford with victory against their promotion rivals.
