Cuthbert started the European defeat at Exeter the previous week, when the Blues shipped six tries but scored four of their own in the opening round of continental competition, and the 19-15 win over the French giants, but he rolled his ankle just 18 minutes into the famous Pool 2 success in the Welsh capital.
That shock success over Jonny Wilkinson, Matt Giteau, Bakkies Botha and co saw the Blues get their hopes of a first quarter-final spot in Europe's top-tier for five seasons back on track and Cuthbert's likely availability for the home tie with their Scottish rivals a week on Friday is a major plus.
Having missed all three of Wales' Dove Men Series internationals with South Africa, Argentina and Tonga, Cuthbert has now stepped up his recovery with his country ahead of Saturday's final Test of the year against Australia. A try scorer in the British & Irish Lions' first Test win over the Wallabies in June, Cuthbert had been expected to miss the entire autumn international campaign but a statement from the Welsh Rugby Union and comments from Blues director of rugby Phil Davies have hinted at a possible early return to action.
"He may be involved next week (this coming Saturday) but I am not sure," said Davies. "We are not sure what his actual status is but it is encouraging for us with the Heineken Cup around the corner."
"The Blues and WRU medical staff have been working closely together to ensure Alex returns to fitness as quickly and safely as possible. He will continue to be assessed by the WRU medics this week," read a WRU release.
Cuthbert's return would be a huge boost for the Blues, especially given that they are currently experiencing an injury curse across the squad. Second row Bradley Davies and centre Cory Allen have already been ruled out following respective shoulder surgeries and fly-half Rhys Patchell is also currently sidelined with a shoulder problem, while lock Lou Reed, prop Scott Andrews and wing Harry Robinson are among the others in the treatment room.
Flanker Andries Pretorious and centre Gavin Evans picked up an ankle problem and dead leg respectively in Saturday night's domestic defeat to Munster, while club captain and former Lions Test hooker Matthew Rees is battling testicular cancer. The various setbacks have left the Blues threadbare in some positions and Davies intends to bring in a couple of players on loan as quickly as possible, with a second row and an inside back top of his wanted list.
"We are looking to bring a couple of players in on loan if we can. We have been busy with that over the last couple of weeks and hopefully we will get things finalised by the middle or end of this week and we can bolster the squad a bit," added Davies.
"We need some cover in the backline and we need some front-five cover with Brad and Lou going down. We need some quality to put in there and that's what we've looked at."
