West Brom caretaker manager Jimmy Shan will remain in charge until the end of the season.
The 40-year-old has overseen four wins in six games since the Baggies sacked Darren Moore last month.
While there was never an official approach, Albion wanted Preston boss Alex Neil but the Scot signed a new three-year deal at Deepdale on Sunday.
Shan said: "I'm happy that we can now move forward with clear planning and direction for the remainder of the season.
"It won't change the work ethic and application of the players and the staff but it enables us to crack on with a clear target in our sights.
"From a personal point of view there is huge, huge pride to be given the responsibility. For me it is a chance to see the journey through that began at the end of last season.
"I've heard it said that with two or three extra games we may have stayed up last season. My aim is to make sure we get those extra games at the end of this season and complete our road back to the Premier League."
