Henson has won 31 Wales caps since his debut in Japan in 2003
Saracens have confirmed they are in talks with Ospreys back Gavin Henson as a replacement for injured fly-half Derick Hougaard.
Wales international Henson, 28, has not featured in a competitive fixture for 19 months.
Sarries chief executive Edward Griffiths told the Daily Telegraph: "It would be wrong to provide a commentary on negotiations with one individual.
"But I can confirm there has been contact between us and Gavin."
Henson, who has played primarily at centre but is also a capable fly-half and full-back, is currently on unpaid leave from Ospreys and last featured for the Welsh region in March 2009.
The British and Irish Lion wants to revive his career in time to be considered for the 2011 World Cup but is looking to sign for a London-based club so he can be close to his children.
Hougaard, 27, ruptured an Achilles tendon in Saturday's Heineken Cup defeat by Leinster and is expected to be out for six months.
Griffiths told BBC Three Counties Radio the club are considering numerous options to replace Hougaard, and a decision would be made in the next few days.
"We're looking at various players who could possibly come in and we're hoping to do something by the weekend," he said.
"We are contemplating various options, one of those options might be to go with the players we have. Another option is to bring players in.
"We're reasonably well covered but we're just looking around and seeing if there are other players who could add something to the squad.
"It's not easy to find players of the required quality but we will cast our net wide and see what it brings."
Sarries could turn to Alex Goode who is making the transition from full-back to fly-half but Richard Wigglesworth and Nils Mordt can also fill the position.
