The problem laid him low after he made less than a handful of Ospreys appearances this term following his recovery from a serious ankle injury suffered last April.

But Henson is now ready to resume full training next week after seeing a specialist on Thursday.

“We are hopeful that Gavin will be available for next weekend,” said Ospreys coach Sean Holley. “We will watch him closely in training during the week.”

The Ospreys though, look certain to be without their Scotland wing Nikki Walker, who suffered a hamstring injury after scoring two tries during today’s 68-8 Liberty Stadium rout of Treviso.

Holley added: “It doesn’t look too brilliant for Nikki, I have to say.

“It appears to be a hamstring injury, and he is laid up at the moment.”

Victory in the Treviso return fixture would leave the Ospreys well-placed in Pool Three ahead of crucial encounters against Perpignan and Leicester next month.

Ireland wing Tommy Bowe led the way by scoring four of his team’s 10 tries as they posted a record Heineken Cup win, comfortably surpassing their 48-17 success against Ulster last season.

Bowe’s four-try haul was also an Ospreys European record, while Walker (2), Lee Byrne, Ed Shirvington, Jonathan Thomas and half-time replacement Shane Williams also touched down.

Fly-half James Hook booted nine conversions, and Holley was delighted with the performance after his international players returned from their November Test commitments.

“We are pretty pleased with that,” he said.

“It is mentally and physically demanding for the players coming back from autumn Tests, and it also says a lot about our squad strength in depth.

“Tommy won man-of-the-match, but I thought James Hook was outstanding.

“James set the tone of our performance - he showed our intent.”

Pool Three whipping boys Treviso trailed 40-8 at half-time, which included conceding a hat-trick to Bowe during 23 minutes.

The second period proved more of a contest as Treviso restricted Ospreys to a Byrne try during the third quarter, but Williams then pounced to give his team an inevitable half-century.

Shirvington and Bowe completed the rout with touchdowns nine and 10, while Treviso had to content themselves with an early Marius Goosen try and Andrea Marcato’s 39th-minute penalty.

It was also the highest Ospreys score in Heineken Cup history, while one more converted try would have left Treviso reeling from their record tournament loss, worse than a 71-5 drubbing suffered against Wasps in 2007.
