Hull are waiting on the results of a scan on George Honeyman ahead of the top-of-the-table showdown with Portsmouth on Friday night.
Honeyman missed Tuesday’s 3-2 defeat at Blackpool with a tight hamstring.
But Hull are hopeful the midfielder, previously an ever-present this season, will be available.
Alfie Jones, Callum Jones and Martin Samuelsen are still sidelined.
Portsmouth are still without Lee Brown, who suffered a torn hamstring against Ipswich last weekend.
Bristol City loanee Cam Pring deputised at left-back in the 0-0 midweek draw with Fleetwood and is set to keep his place.
Pompey boss Kenny Jackett has no other injury concerns.
Jackett’s side would climb above Hull into top spot with a victory.
