Leicester Tigers have signed second-row forward Dom Barrow from Aviva Premiership rivals Newcastle Falcons ahead of the 2015/16 season.The 22-year-old Barrow is a former captain of England Under-16s and Under-18s, and a World Junior Championship winner with England Under-20s in 2013.   A graduate of the Leeds academy, he made his senior debut as a 17-year-old there before moving to Newcastle Falcons in 2013 and went on to make 26 appearances for the Kingston Park club.   Leicester Tigers director of rugby Richard Cockerill said: “We’re delighted to be able to add Dom to the squad for next season. He is a big, athletic second row who has already gained Premiership Rugby experience and we think he can only improve working with a very good group of second rows here including Graham Kitchener, Ed Slater, Sebastian De Chaves and our new signings Mike Fitzgerald and Mike Williams.”   Tigers have previously announced the addition of Greg Bateman, Peter Betham, Mike Fitzgerald, Opeti Fonua, Jon Kitto, Lachlan McCaffrey, Brendon O’Connor and Mike Williams to the playing squad for 2015/16.
