Hull centre Kirk Yeaman has been ruled out for six weeks with a broken thumb.
Yeaman, 29, suffered the injury diving on a loose ball during Friday’s 52-0 win over Castleford on Friday.
Hooker Aaron Heremaia is also a doubt for Saturday’s match against Huddersfield with a rib injury.
However, the Kiwi’s injury isn’t as bad as first feared.
Back-rower Danny Tickle has been handed a one-match ban, after pleading guilty to punching during the game against the Tigers.
