The Ospreys forward returned home early from Wales’ training camp in Poland and failed to make last weekend’s clash with Argentina due to injury.
But Jones took part in Wales’ training session on Tuesday and if fit, can’t wait to play a part against the South Sea Islanders.
“I’m desperate to play, I genuinely love playing rugby and playing for Wales,” said the 67 times capped forward.
“I was bitterly, bitterly disappointed not to be involved last week. Just to be sat watching is a tough place to be but I’d love to be fit and be in contention.
“We need to get back to winning ways really. We need to put a few things right tactically and technically and we need to get a good result under our belt.”
Now 31, Jones has had a number of injuries this season. As well as his shoulder problem, the Osprey suffered what he described as a big bang to his leg in a Heineken Cup clash with Leicester last month.
After losing Alun Wyn Jones and Josh Turnbull to injury against Argentina, Rob Howley faces selection issues in the pack. But Jones believes injuries are part and parcel of the game these days.
“That’s the modern game, it’s become attritional now,” he added.
“In this day and age you’re almost fortunate to come away from a game without a bump or a bang, that’s what it’s become.”
Jones’ return from injury provides added experience to a Welsh squad determined to make amends for last Saturday’s defeat.
“I like to think I can add value, I’ve been in similar situations quite a few times over the last 10 years at both club and national level so it’s nothing I haven’t seen,” he said.
“Some of the guys won’t have faced this in their career so far. We’re talking about guys who have got relative experience in the number of caps but the majority of them will have come on the back of a successful 12 or 18 months so they possibly haven’t encountered this pressure and expectation.
“There’s a real desire to put it right this week which is what we need.
“You can only put it right collectively. It’s not about a big performance from one individual. It’s about making sure we take control of what we can.
“If everyone does their role and they do it well and execute that properly then we think we’ll come out on top.”
Jones knows Samoa will provide anything but an easy challenge though and expects a huge physical battle.
“It’s tough and it’s uncompromising. They’re a nation that likes confrontation,” he said.
“When you face teams like that first and foremost you have to match that because if you don’t, you don’t get enough ball or the sorts of things that dictate the outcome of a game.
“The minimum is to match that physicality and that desire. They play with their heart on their sleeves.
“When teams are in it at the 60 minute mark it’s very difficult to pull away but if we can keep the scoreboard ticking over and match that physicality I think we’ll do well.”
