Wasps have confirmed the signing of prop Tom Bristow from Leicester Tigers.Loosehead Bristow, 23, has made 14 appearances for Tigers since moving from London Welsh at the start of the 2013/14 campaign.   Bristow said: "I've thoroughly enjoyed my time at Leicester Tigers. I feel I've developed a lot and I'd like to thank them for my two years there. Boris Stankovich in particular helped me massively with my scrummaging. The atmosphere with the boys there, seniors and younger guys, was top notch.” Wasps have also announced the signing of centre James Downey who has been with the club as injury cover since February, centre Brendan Macken from Leinster and scrum-half Jamie Stevenson from London Scottish.
