Three points, improved goal difference, and momentum in the Championship table are at stake for both clubs.
The match will influence league position, playoff prospects, short-term confidence, and matchday revenue as the season moves toward its final weeks.
Millwall's squad and Hull City's squad determine the outcome through their starting XI and bench contributions.
Club managers, key attackers and defenders, the match referee, and the home crowd at The Den all exert measurable influence.
Recent form, injury lists, and managers' selection choices are the immediate levers shifting pregame expectations.
Tactical approach, set-piece effectiveness, head-to-head history, early bookings or red cards, and weather conditions on matchday combine to change in-game probabilities.
May 11 kickoff will be preceded by final team sheets and warmup reports that confirm starters and late absences.
Watch for last-minute injury updates, the announced referee, weather forecasts, lineups, and in-play triggers like an early goal, penalty, or sending-off.
