Hull City's deal for Lokomotiv Moscow striker Dame N'Doye was among the last of the winter transfer window.
The 29-year-old, who scored 27 goals in 66 games for Lokomotiv, has agreed a two-and-a-half year deal, with the option of a further year.
Hull vice-chairman Ehab Allam said: "It's taken us three weeks and we almost missed the deadline so it's been fantastic news to get it over the line.
"It's just been a long day of negotiations, very stressful. It's broken down on several occasions but Steve was in France with the player and he managed to get it over the line."
