He said they wanted to bring Richards back from Australia for the match, but existing commitments prevented him from travelling.
“But we’re hoping to get him back over for a game next year,” added Collinson.
Richards left Wigan at the end of the double-winning 2013 campaign to return to his former club Wests Tigers.
After two season in the NRL, the goal-kicking winger returned to Super League this year and made an appearance against his former club at the DW in the opening game.
