Queens Park Rangers interim manager Neil Warnock will miss his side's trip to Middlesbrough due to "personal reasons," the club have revealed.
Warnock, 66, was placed in charge of the Championship outfit after Chris Ramsey was sacked on Nov. 4.
Kevin Blackwell, who was brought in to assist Warnock, will now take charge of QPR at the Riverside Stadium on Friday night.
It was reported this week that Warnock expects to be in charge of the Loftus Road club, who are 13th in the Championship, for two further games.
Former Leicester City boss Nigel Pearson and Burton Albion manager Jimmy Floyd Hasselbaink have both been linked to the post.
Warnock returned to QPR in an advisory role in October after he was sacked by Crystal Palace last year.
