The captain has missed the club's last three matches because of a hamstring complaint.
However, providing that he suffers no setbacks, Solbakken believes that the midfielder could be fit enough to take on Leicester City next weekend.
"He'll be back in training next Tuesday so he can have a good few days' training before the Leicester game," said Solbakken.
"He's been out for two or three weeks but he was nearly fit and he broke down. I think the medical team are afraid of him breaking down so they want to give him two or three extra days.
"But I think he will be in contention for Leicester."
A return for Henry is likely to see David Davis drop down to the bench.
