The news is a major blow for Lyn Jones, his side travel to the north of England to take on take on tough English outfit Leeds on Sunday, but will have to make do without the brilliant youngster, who broke the hand in his side's Celtic League loss to Leinster last weekend.
The injury will put Henson on the sideline for up to six weeks, and virtually kills off his hopes of making Steve Hansen's Six Nations squad, with the national coach unlikely to include players he hasn't had a good look at.
But the injury to Henson opens the door for Springbok signing Stefan Terblanche, to make an immediate impact. The Springbok star arrives in Wales this week, and is registered to play in the Heineken Cup .
Jones said: "Stefan has a strong all-round game, but his greatest strength is his natural speed, which will be useful not just in attack, but also in defence."
Terblanche's defence will be a welcome boost for the side, who leaked six tries against a Brian O'Driscoll-inspired Leinster last Saturday.
Another fullback option for Jones is talented former Wales international Adrian Durston, while Shaun Connor will take over Henson's goal-kicking duties.
