Writing in his programme notes ahead of Saturday evening's League clash with Manchester United, Short said: "We now have a very important decision to make.
"Our only consideration in making that decision is what is best for the club.
"In doing so, we feel the weight of the entire city and beyond, along with the history of this massive football club.
"The appointment of a replacement head coach is our priority and I urge you to ignore the speculation in the media about the selection process, because most of it is completely wrong.
"It has been a terrible start to the season and we are now living with the inevitable disruption related to parting company with our head coach.
"We owe great thanks to Paolo Di Canio for keeping us up last season. He came in and provided the fire that we needed to fight for the points necessary to stay in the league.
"I appreciate that opinions are mixed amongst our fans over whether he should have been replaced. Again, this decision was based on what we felt was best for the club.
"We wish Paolo the best in his future managerial career."
