The player was seen in a nightclub, which his club chairman felt was a “selfish” act.
“It’s about getting the right people in, the right culture at the club, and Greg let us down this week,” he told BBC Humberside.
“He can’t stay out of the nightclubs of Hull when he shouldn’t be in there. That’s the fourth player this season.
“He may have helped us today if he were playing. But he wasn’t playing for his own selfish reasons.
“It’s trying to drill out of the club that culture and mind-set.”
There are also more new recruits on the way to the club, according to Hudgell. The Robins recently signed Darrell Goulding from Wigan for next season, and more are on the way, it would seem.
“We’ve signed two players and we’ve got a couple more signings in the pipeline,” he added.
“The hope and expectations is that they’re going to enhance the playing group, because they need to. We’re trying to improve what we’ve got.”
