More than 145,000 had sold the AFC Bournemouth striker after a run of five matches without a goal.
But the Cherries' home meeting with West Bromwich Albion is one of only four fixtures taking place in Gameweek 31.
That has helped him become the fourth-most bought player ahead of Saturday’s 14:00 GMT deadline, with over 96,000 new owners.
Injury doubts surrounding Wilson's team-mate Joshua King (£7.0m) have also contributed to that boom.
A neck problem makes the Norwegian striker, who has scored in two of his last three starts, doubtful for Saturday's encounter.
King was restricted to a 23-minute appearance from the bench against Tottenham Hotspur in Gameweek 30.
It means Wilson is likely to carry the main goal threat against a Baggies defence with only one clean sheet from their last 14 away matches.
Recently handed a central-midfield role, Rooney is without a goal or an assist since Gameweek 18.
But with Sigurdsson sidelined, he could be shifted forward behind lone striker Cenk Tosun (£6.8m).
Owned by 11.3% of FPL managers, Rooney scored the winner and collected maximum bonus in a 1-0 victory over Stoke in Gameweek 1.
Meanwhile, Baines is likely to be handed set-pieces in Sigurdsson’s absence.
The left-back may also be on penalties after Rooney’s miss against Brighton & Hove Albion last weekend.
Part of just 5.9% of FPL squads, Zaha offers a new differential option in midfield, particularly for managers activating the Free Hit chip.
The winger has scored or assisted in eight of his 20 Gameweek appearances under manager Roy Hodgson.
