Scrum-half Luke Baldwin will not play again for Bristol this season after agreeing a summer move to a rival Championship club.
Baldwin signed from Saracens in December 2013 and has made nine appearances this term, scoring one try.
The 24-year-old has been linked with a move to Worcester Warriors, who are a point above Bristol in the table.
Earlier this month, winger Andy Short was put up for loan after announcing his intention to join Warriors.
Short has now joined Premiership side London Irish until the end of the current season and will move to Sixways in the summer.

Bristol director of rugby Andy Robinson said: "We offered Luke a contract here and wanted him to stay.
"We felt he had a part to play for the remainder of the season, but unfortunately that will no longer be the case.
"Like Andy Short, we have no choice but to follow similar action with Luke. He won't play any further part in our campaign."
Former Bedford player Baldwin released a statement through the club which read: "As I'm sure many of you can appreciate, there is only a small window of time in professional sport and, as a result, tough decisions have to be made.
"I feel there is a good opportunity for me to go and play regular rugby, something that was not always possible at Bristol.
"This was purely a rugby decision and bears no reflection on my fellow team-mates, management or the club."
