Pearson takes over from Quique Sanchez Flores — who only took over from Javi Gracia in September — who left his post at Vicarage Road with the Hornets sitting 20th out of 20 teams in the PL table, already seven points adrift from safety. Pearson’s contract runs through the end of the season.
The 56-year-old Pearson, who last managed in the PL with Leicester City in 2015, was most recently in charge of Belgian side OH Leuven before he was fired in February.
Pearson won’t take charge of Saturday’s game against Crystal Palace (Watch live, 10 a.m. ET, on NBC Sports Gold). Interim manager Hayden Mullins will see out the week’s preparations and manage the team before handing the reins to Pearson on Sunday.
