Warriors can confirm that prop Jerome Schuster has joined the club as injury dispensation for Jeremy Becasseau until the end of the season.
The 28-year-old arrives at Sixways from Leicester Tigers after Becasseau underwent surgery on a neck injury.
Schuster has been at Leicester since last summer after joining from French side Perpignan.
Capable of playing on either side of the scrum, Schuster picked up a French Top 14 title with Perpignan in 2009 and made his Test debut for France against Fiji in November 2010.
Warriors Director of Rugby Dean Ryan said: “With the injury to John Andress and the fact that Euan Murray has only recently returned from a lengthy lay-off, it was important to bring in a tighthead prop for the rest of the season and I am delighted that we are able to recruit someone of Jerome’s experience.”
