Three youngsters have signed new wasps contract as it was revealed. Full-back Wallace, 19, has made five first-team appearances and back row Jones, also 19, made his debut against Newport Gwent Dragons two weeks ago.
Meanwhile 18-year-old Holmes has yet to make a first team start but has featured as travelling reserve.

He added: “All thee players have already contributed to the Wasps cause, featuring in the A team and in training week-in week-out, whilst Jack and Sam have secured game time with the first XV.
