Harlequins have signed Saracens hooker Max Crumpton on loan until the end of the season.
The 20-year-old has cut short his loan spell Plymouth Albion, where he made four Championship appearances and featured in the British & Irish Cup.
Crumpton has represented England at Under-16, Under-18 and Under-20 level.
Harlequins have injures to three of the four hookers at the club and Crumpton has been named among the replacements for Saturday's match at Bath.
"Great to announce that I'm joining Quins for the rest of the season," Crumpton wrote on his Twitter page.
"Thanks to all the players and fans at Albion for making my time at the club very enjoyable."
