Meanwhile, electric winger Olowofela is currently plying his trade on the World Rugby Sevens Series with England, and will arrive at Franklin’s Gardens this summer in time for preseason.

“Ryan, Lewis and Karl are obviously very different players, but we believe they are great acquisitions for us and are confident all three will make a significant impact next year,” said Boyd.

“Karl caught our eye earlier this season while some of our other tightheads were injured and he took his opportunity superbly, and Lewis has also been really impressive – as you might expect of a serviceman, his work rate and attitude are top class.

“Ryan seems to be going from strength to strength with England Sevens so we are really excited to get him into our environment and see what he can do in XVs footy; clearly he is a high-skill player with bags of pace, so I’m sure he can be a supporter favourite here at the Gardens.”

Olowofela, 20, came through Leicester Tigers Academy – alongside identical twin brother Jordan – before turning his attentions to Sevens rugby and the world stage.

After making his England debut at the Rugby Europe Grand Prix Sevens Series in Moscow in 2017, he progressed onto the World Series the following year and has been a regular fixture in the side ever since.

This season Olowofela has scored 12 tries in 24 matches for England, and is set to reach 50 Sevens caps overall before the end of the current campaign.

Rifleman Bean has been on two tours of Afghanistan during his time in the military services, but also worked his way up through the Army’s age-grade teams and featured in the 100th anniversary match between the Army and Navy at Twickenham in 2017.

The 125kg lock has balanced his career while playing for Moseley in National One in recent seasons, also turning out twice already in Black, Green and Gold for the Wanderers this term against Worcester Cavaliers and Wasps A.

Bean, 26, was on loan at Worcester Warriors at the start of the season and featured for the Sixways outfit in the Gallagher Premiership, before landing a switch to Northampton.

And 21-year-old tighthead Garside began his rugby career at Oaklands College and featured in the RFU’s AASE League against the likes of future Saints teammate James Grayson.

He became Saint number 1997 back in October when he made his full debut against Bristol Bears in the Premiership Rugby Cup, and has four first-team appearances to his name so far – including featuring in the Gallagher Premiership triumph over Wasps at Franklin’s Gardens.

At club level Garside joined National One outfit Ampthill & District from Old Albanians in 2017, and has also represented Hertfordshire and England Counties.
