Hull have appointed Ruben Selles as their new head coach.
The Spaniard has left his job as Reading manager and signed a two-and-a-half year deal to take over at the MKM Stadium, with the club retaining the option to extend the deal by a further season.
He replaces Tim Walter, who was sacked on November 27 after just 18 games in charge.
Former Tigers defender Andy Dawson - brother of Sky Sports' Michael Dawson - had been in charge in the interim and he oversaw the 3-1 defeat to Middlesbrough at the Riverside Stadium last weekend.
Hull are currently on a run of five consecutive Championship defeats and are without a win since October 1. They sit 22nd in the table as a result, two points from safety.
Selles, 41, was named as Paul Ince's successor at the Madejski Stadium in June 2023 and he guided Reading to a 16th-placed finish in their first season in the third tier since 2001/02.
His exit will come as a significant blow to the Royals, given they sit sixth in Sky Bet League One ahead of a busy Christmas period, having won five of their last eight league games.
