Worcester have confirmed 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 the start of this season 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.
"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," said Warriors director of rugby Dean Ryan.
