Northampton Saints prop Luke Green has signed a contract extension for next season with the reigning Premiership champions.

The 23-year-old has made 15 appearances so far this season, having arrived last summer following a spell in the United States with San Diego Legion.

A former England Under-20 international, he began his career with London Irish and played for Championship club Ampthill before heading across the Atlantic.

“Luke first came into the club for preseason before the 2023-24 campaign, and was really impressive – both in terms of his physical attributes and the way he applied himself,” said director of rugby Phil Dowson.

“He then went away to San Diego, which only finished in August, so Luke didn’t have a long pre-season with us this year, but again what we did see in that time was his strong appetite to get better.

“Luke’s a very coachable player. It speaks volumes that he’s been getting so much gametime, and he’s there on merit.”

Three of Green’s appearances came in the European Champions Cup and he said: “It’s a great club, a great environment, and a place where I feel everyone wants to improve and get better, from top to bottom.”

Northampton, meanwhile, have signed Australian teenager Charlie Ulcoq on a deal to the end of the current season.

The 18-year-old back row, formerly with New South Wales Waratahs, joins the club’s senior academy.
