Northampton’s uncapped tearaway loose forward Teimana Harrison is expected to be named in a provisional England training squad ahead of this summer’s tour to Australia on Sunday.

The 23-year-old New Zealand born flanker or No.8, who has an English father, has excelled for Northampton this season and will be included in a squad of around 20 players who will convene for a three-day training squad in Brighton beginning on May 16.

The squad will not include players from any of the four remaining Aviva Premiership teams left in the play-offs – Saracens, Exeter, Leicester and Wasps – but Harrison’s inclusion will spark significant interest after a breakthrough season with Saints.

Harrison, scouted by Saints team-mate Dylan Hartley after he spotted him playing for his old school Rotorua High School in New Zealand in 2011, can play across the back row and Northampton director of rugby Jim Mallinder believes he is ready for the step up to international rugby.

‘He is definitely in the frame,’ Mallinder said recently.

‘He has been improving for a few years but I think we have seen a level of consistent performance from him this year to suggest that he go on and play at a higher level.’

Sam Underhill, who has been impressing for the Ospreys this season, is unlikely to make the England squad

Hartley is also expected to be included – despite not starting a game since being knocked out in England’s Grand Slam victory over France on March 19 although Mailsport understands Ospreys uncapped flanker Sam Underhill will not be named.

The squad will begin preparations for the one-off Test against Wales at Twickenham on May 29 before the three Test tour to Australia which see 6ft 3in, 16 stone Harrison given a chance to prove himself at openside.

‘Teimana plays well for us at eight but I think at international level seven will be his position,’ said Mallinder.
