Hull have parted company with head coach Leonid Slutsky six months after appointing him as the English Football League's first Russian boss.
Slutsky, 46, who replaced Marco Silva at the KCOM Stadium in June, has won only four of his 19 Sky Bet Championship games in charge.
Saturday's draw at Sheffield Wednesday left the Tigers, relegated from the Premier League last season, 20th in the table, three points above the bottom three.
