Manager Chris Ramsey rues the "lapse of concentration" he blames for 10-man QPR conceding a late goal to lose 2-1 away at Hull.
Nickica Jelavic put Hull ahead before QPR had Joey Barton sent off. Charlie Austin then equalised for the visitors but Dame N'Doye grabbed a late winner for the Tigers.
Barton's red card followed seven yellow cards in his previous seven league games.
