Henry is one of four Wolves players back in contention for Sunday's home Championship clash against Leicester.
The midfielder has missed the club's last three matches with a hamstring strain sustained against Barnsley last month but returned to training earlier this week.
Full-back Kevin Foley is also back after his lengthy absence with a knee problem while Razak Boukari (hamstring) and Bjorn Sigurdarson (back) are fit having missed the defeat at Cardiff last time out.
Manager Stale Solbakken has had plenty of time over the international break to ponder his line-up against the Foxes, kick-off 1.15pm, with Wolves' 3-1 defeat to the Bluebirds leaving them with one win from their opening four league games.
Solbakken recalled his first-choice XI in the Welsh capital, making 10 changes from the second-string line-up who saw off Northampton in the Capital One Cup and further alterations could well be made this weekend.
Goalkeeper Wayne Hennessey (knee) is tipped to return around the end of October.
Ritchie De Laet is expected to be fit for Leicester.
De Laet missed the 1-0 home win over Blackpool prior to the two-week international break, having to be replaced in Nigel Pearson's starting line-up after injuring his back in the warm-up. The defender has since trained and should be fit.
Richie Wellens continues to work his way back to full fitness following knee surgery. The midfielder played 30 minutes for the development squad towards the end of last month and he has been pencilled in for another run out next week.
Likewise with defender Zak Whitbread, who has been building up his fitness since arriving at the club on a free transfer from Norwich in the summer.
Marko Futacs (Hungary U21s), Andy King (Wales), Anthony Knockaert (France U21s), Ben Marshall (England U21s), Kasper Schmeichel (Denmark), Sean St. Ledger (Republic of Ireland) and Martyn Waghorn (England U21s) have all returned from international duty unscathed and are in contention for places in the squad.
