There had been concerns that Sako would miss out on the contest, but it seems the 26-year-old will be available for selection.
That will be a big boost for Wolves, as the Mali international is one of their key players and he could present a big threat to the Nottingham Forest defence.
Forest have improved considerably under the guidance of Dougie Freedman, but Wolves are the Championship's form side and with Sako at their disposal they will pose a huge challenge for the Reds.
Sako has scored 12 goals and claimed four assists over the season so far, whilst he has also proved a huge source of creativity.
Sako has made 48 chances for his teammates this season and also has averaged over three shots per game.

It means that the match could come down to how well Forest are able to deal with Sako's threat and if they can't, their playoff hopes could be over.
Forest need to win the bulk of their remaining fixtures if they are to make it into the top-six, and their match against Wolves provides them with one of their toughest remaining tests.
Freedman's side do have a winger in Sako's mould themselves, though. Michail Antonio has torn the Championship apart this season and the hope is that he can continue to do damage on Friday.

Antonio has actually outperformed Sako this season, scoring 12 times and racking up 11 assists in a campaign which has been the most impressive of his career to date.
As a result, the game between Forest and Wolves could well come down to which team deals with the other's main attacking weapon best - and both Sako and Antonio will be determined to inspire their respective employers to three points.
