[2] His team-mates that day included future senior Wales regulars Rob Evans and Samson Lee as well as several other players who would go on to earn senior Wales caps including Tom Prydie, Dan Baker, Eli Walker and Matthew Morgan, as well as future Scotland international Luke Hamilton.
Jenkins would have to bide his time before making his senior Wales appearance, in part due to intense competition for places in the Wales back row from the likes of Sam Warburton, Dan Lydiate, Justin Tipuric, Josh Navidi and Aaron Shingler.
He finally made his debut aged 23 on the 2016 tour of New Zealand, coming off the bench in all three tests.
Unfortunately, during the final match against South Africa national rugby union team of the Under Armour Autumn Series, Jenkins suffered from a torn AC, MCL and numerous damages to the tendons in his left knee.
This left him in rehabilitation for an extended period, making him unavailable for the 2019 Rugby World Cup.
