John Eustace is closing on a return to management with Blackburn Rovers.
The Danish manager is believed to have offered to resign with Rovers mired in an eight-game winless Championship run.
Just one season after finishing seventh, the side are currently languishing 18th in the table.
The club did not allow Tomasson to appear at his press conference prior to Saturday’s 2-1 defeat by QPR and it is thought that his 20-month tenure will soon be over.

Once that is concluded, Blackburn are expected to install Eustace as their new boss, ideally ahead of Saturday's clash with Stoke City.
The 44-year old lost his job at St Andrews as the club made an ambitious move for Wayne Rooney.
The England international's own stint in the dugout lasted just 15 matches in charge, which saw Rooney win just 10 points from a possible 15 and plummet down the table from sixth to 20th.
Eustace has also had experience with QPR and the Republic of Ireland.
As discussions look to reach a conclusion over 47-year old's Tomasson's job today, Blackburn are also awaiting news from the EFL board over their proposed signing of Duncan McGuire from Orlando City.
Blackburn declared the striker had signed on loan on deadline day only to be told he couldn't be registered owing to an administrative error.
