The winger picked up a hamstring injury during the club's Championship clash with Preston on Saturday.
The 26-year-old was forced off after just 18 minutes of the side's 2-1 home defeat to Preston on Saturday, meaning that he has become the club's eighth player that is currently sidelined with injury, the Mail reports - though Kortney Hause is closing in on a return to the first-team having also been struck down with a hamstring problem.
It seems highly likely that Wolves' injury crisis has been a major factor behind the club's recent run of form, which has seen their hopes of reaching the play-off places take a serious dent.
Kenny Jackett's men have not won in their last five games, so the boss would have undoubtedly been looking to players like Henry to help them end their slump, and perhaps give them a chance of clawing back the 11 point gap that separates them from the top six.
The midfielder's tally of seven league goals makes him the club's top goalscorer - although former striker Benik Afobe managed nine strikes before his departure in January - while his four assists makes him the side's second most productive player in that department behind Jordan Graham, who unfortunately for Wolves, is also out on the sidelines.
