The Strictly Come Dancing star ended a 19-month self-imposed break from the game by joining Saracens last month.
He was in the stands to watch his new club on the weekend and witnessed their 22-all LV=Cup draw with Northampton.
It was the first full game the former Osprey has watched since taking his sabbatical and he revealed he is only three to four weeks away from being fit enough to play his first game for the Aviva Premiership outfit.
That could ironically see the 2005 tourist make his comeback against the side he last played against. Henson picked up ankle and Achilles injuries in the EDF Energy Cup against the Cherry and Whites back in March 2009.
Now he could be in line to banish his demons by facing Gloucester on November 27, if not Harlequins on December 4.
"I have to be patient and I'm probably three or four weeks off playing," said 28-year-old Henson.
"Every time I watch a game of rugby I just want to be out there. It was fun to watch and I can't wait to be out there with them. That was the first game of rugby I have watched in about 18 months. I enjoyed it, it looks like nothing much has changed."
Henson featured in four games during the 2005 tour of New Zealand, scoring two tries in the process.
