Wasps have bolstered their squad with the signings of Stuart Commins and Charlie Hayter.
Scrum-half Commins has arrived at Adams Park to provide cover for Joe Simpson, who will be away for the next fortnight with the England Saxons.
Centre Hayter, meanwhile, joins Wasps from RFU Championship side Moseley, where he has been an ever-present this season. He has previously played for Worcester.
"These are two positions in which we needed to add depth," London Wasps director of rugby Dai Young told the club's official website.
"We're losing two centres - Andrea Masi and Elliot Daly - to international duty in the coming weeks and with a long-term injury to Lee Thomas, adding another centre to the squad was important.
"Charlie has been very good at Championship level so we're looking forward to seeing what he can do.
"With Joe Simpson with the England Saxons for a few weeks combined with the fact that we haven't replaced Nic Berry, who retired earlier in the season, we also needed another scrum-half and Stuart has good experience and has fitted in well so far."
