Sale have brought in Leeds hooker Andy Titterell on loan in a deal that sees scrum-half Will Cliff and centre Jordan Davies move the other way.
Titterell, who was part of the Sharks side that won the Premiership in 2006, will rejoin the club until the end of January before heading back to Leeds to spearhead their Championship effort.
Cliff and Davies will remain with the Yorkshire club for the rest of the season.
Titterell made 122 league appearances during his first spell with Sale and could come into the squad for Sunday's Amlin Challenge Cup meeting with Agen.
The former England international said: "This was a very difficult decision to make because we are building something special at Leeds Carnegie.
"However, I know the relationship with Sale Sharks is an important one for the club and I am looking forward to playing for the Sharks until the end of January."
Titterell makes the move with Leeds currently seventh in the Championship table, and their chief executive Gary Hetherington said: "This is not a decision we have taken lightly as Andy is a huge part of our club and where we want to be in the future.
"However, we recognise the fact that we have an excellent relationship with Sale and the fact that Andy would have no interest in playing for any other Premiership club other than the Sharks, who he still has a close bond with.
"We already have Tommy Bell and Iain Thornley on loan from Sale for the entire season and both players have been outstanding for us, and the addition of Will Cliff and Jordan Davies will strengthen our squad in key positions for our promotion push in the new year."
