Tom Cowan-Dickie, brother of England international Luke, has joined the Ospreys as injury cover for hookers Dewi Lake and Sam Parry.
Wales international Lake suffered a knee injury against Leicester Tigers on Friday night, just days after being named in Warren Gatland's Six Nations squad. Wales are now waiting on an injury update for the 23-year-old, but are expecting him to miss some, if not all, of the tournament. Ospreys hooker Scott Baldwin has been outlined as his Wales replacement.
Parry has also been struggling with a shoulder injury, leaving Toby Booth's options at hooker pretty low. As such, Cowan-Dickie, who left Leicester at the end of December, has been signed on a short-term deal.
