Jacob Umaga

Wasps flyhalf Jacob Umaga has been added to the England squad for this weekend's Six Nations decider in Italy and next month's Autumn Nations Cup.

The 22 year old, who is the nephew of former All Black Tana Umaga, was first called up to the England senior side in January but is yet to make his test debut.

Mike Umaga, who played 13 tests for Manu Samoa in 1990s, said his son is a pretty laid back character but it definitely up for the challenge.

"We're really buzzing for him, so proud of what he's done up until this point," he said.

Umaga, the son of Mike and nephew of Tana Umaga, got his first call up to the England senior side in January, but hasn't played.

First-five Joe Simmonds was man of the match in Exeter's Champions Cup victory over Racing 92 last week and had another perfect day with the boot in the weekend's Premiership final win over Wasps.

However, coach Eddie Jones has included uncapped Wasps number 10 Umaga as backup to Owen Farrell, with George Ford absent through injury.

Jones included 22 players involved in Japan, but many of the absentees are carrying injuries, including No.8 Billy Vunipola, who broke his arm for the fourth time on Sunday.

Prop Dan Cole, who had a torrid time in the final defeat by South Africa, was an expected omission, while versatile back Jack Nowell was also missing.

Of the uncapped group, Tom Dunn, Ben Earl and Ollie Thorley have been involved in previous squads, while Fraser Dingwall, George Furbank, Alex Moon, Will Stuart and Jacob Umaga are called up for the first time.

Former All Black midfielder Fekitoa, in his first season at the English club, has credited the 21-year-old first-five for transforming Wasps' attack in the absence of of another ex-Kiwi international, Lima Sopoaga, due to illness.

Sopoaga is now back in contention for selection but has struggled to make an impact since signing with Wasps in 2017 and Umaga's impressive form will only have put more pressure on the 18-test All Black.

RNZ reports Jacob Umaga, who is the son of Tana's brother Mike, has previously played for England at under 18 level.

The Wasps first five has been named to start for England under 20's against Wales this weekend.

The 18-year-old Umaga came on as a replacement at centre against France last weekend and recently made his senior debut at fly half for Wasps in the Anglo-Welsh Cup.

Jacob Umaga was born in England.
