Paul Dickov will seek urgent talks with the club’s hierarchy next week following the collapse of John Ryan and Louis Tomlinson’s takeover.
The Scot had been promised a playing budget to match League One’s biggest spenders by Ryan and Tomlinson.
He is understood to have lined up several deals based on those figures and dependent upon the takeover being finalised.
But this week’s collapse of the takeover - due to new ownership regulations introduced by the Football League - means that, for the second successive summer, Dickov must now put Plan B into operation.
Upon his return from Portugal, Dickov will seek confirmation of exactly what funds are at his disposal at the earliest opportunity by speaking to chief executive Gavin Baldwin and co-owner Terry Bramall.
Sources told the Star at the end of last season that the playing budget was set to be slashed to £2 million as a result of relegation.
At the time Rovers denied that would be the case and said Dickov would be given an appropriate budget to match his straightforward brief - to get promotion back to the Championship at the first attempt.
Nevertheless, a major question mark now hangs next to the future of several existing players, and also those out of contract and on trial.
Richie Wellens had held informal talks about a new deal, subject to the takeover going through.
Free agent James Coppinger had agreed a new contract but that was also subject to the successful completion of Ryan and Tomlinson’s takeover.
While Dickov had hoped to recruit ‘six or seven’ new faces based on the budget proposed by the prospective new owners and has ran the rule over seven trialists so far this pre-season.
Doncaster currently have 11 players under contract, with no senior goalkeeper on their books.
Among them are Paul Quinn, who failed to report back for pre-season training, Wellens, who like Quinn has a relegation release clause, and Rob Jones and Jamie McCombe who are both still recovering from long term absences.
Ryan and Tomlinson failed to provide a business plan and to demonstrate that the funding was in place to deliver that plan, said the Football League.
