Allan Jacobsen acknowledges that a rugby player's fortunes can fluctuate rapidly from heady highs to morale-sapping lows but admits he is determined to experience an enjoyable return to Edinburgh duties when he packs down against Munster's famous front five on Saturday (kick off 7.30pm).
The 29-year-old prop's World Cup ended in early heartbreak when he ripped a hole in his calf muscle during Scotland's opening match against_Portugal in September.
But his dogged determination and unswerving focus on returning to match fitness has helped the popular front row forward stage a first comeback ahead of schedule.
Accordingly, Jacobsen, universally known by his nickname "Chunk", is thrilled to be back in action so soon after suffering the set-back and concludes that any player's luck can change full-circle in a small timescale.
Jacobsen said: "After the injury I just want to get back into it " I can't wait. Sometimes that is just the way it goes in rugby and I"m lucky.
"I was devastated at the time when I got injured at the World Cup, but I"ve seen a lot of guys over the years, who have been out for a much longer period of time like a year for example. In those terms, it wasn't a bad injury, it was just really bad timing."
Despite being picked to line up alongside new recruits Gavin Kerr and hooker Ross Ford, Jacobsen says it will be a case of friends reunited in Edinburgh's front row as opposed to three strangers packing down at the coalface.
He said: "I have played and trained with Ross for a few years now and I also know Gavin and Smithy (Craig Smith) well from Scotland.
"I have played with and against Gavin since we were about 16 and I first played against Smithy when I was about 13.
"We have got good strength there. When you look at the props we have got in the squad it is unbelievably strong. So I realise it is going to be tough to get a game."
The first test for the new-look front row is the obstacle of overcoming Munster's revered pack and, although Jacobsen understands the sheer magnitude of the task ahead, he also stresses he is excited by the challenge.
He added: "John Hayes is probably one of the most experienced props in Britain and Ireland at the moment. He is a legend at Munster, so it is going to be a tough challenge.
"Playing any of the Irish teams on their home soil is always tough. As it is in any away game in the Magners League, but Munster seem to have that extra factor at home. They just seem to have that extra edge and they are renowned for their forward play.
"But they are not unbeatable and we have won there a couple of times. In order to beat them away from home you need to front up and perform in the set-pieces and that is what we are aiming to do."
