Bath have signed Bristol hooker Chris Brooker on loan until the end of the season.
The 30-year-old, who had a spell with Bath between 2006 and 2010, has made seven appearances this season.
Director of rugby Todd Blackadder said: "We're really pleased to have been able to bring someone who has as much experience as Chris in."
Meanwhile, front-rower Shaun Knight and hooker Michael van Vuuren have extended their stays at The Rec.
Knight, 27, joined Bath on loan from Newport Gwent Dragons in September and will now remain with the club until the end of next season.
Van Vuuren, 25, joined from Leicester in 2016 and has signed a new two-year deal.
