Wigan Warriors coach Adrian Lam is back in Australia following a death in the family.
Assistant John Winder led training on Wednesday morning and took the weekly press conference in the afternoon.
Lam will be back on Thursday - in time for Sunday’s game v Hull KR.
And Winder doesn’t think will disrupt preparations.
He said: “In my time at the club we’ve been in similar positions but we have a strong leadership team here and it’s about everyone pulling together.”
Lam's predecessor, Shaun Wane, once missed a match because of knee surgery - Winder stepped up and took charge.
And when Wane was assistant coach, he held the reins for two matches when Michael Maguire returned home following the death of his dad.
