Dragons Head Coach, Kingsley Jones commented: “We are happy to cooperate with the Scarlets and assist them in their current situation.
“This is a fantastic opportunity for Luke to gain experience and accelerate his development by gaining some invaluable experience in the Guinness PRO12 and potentially European competitions.
He continued: “The Dragons are well served at loose head with new signings Sam Hobbs and Tom Davies available, plus Phil Price is due to return from injury shortly. However, should an issue arise there is a facility to recall Luke to the Dragons squad.”
