Worcester Warriors have emerged as favourites to sign Wasps and England flanker James Haskell.

The 32-year-old back-row forward will be leaving the Ricoh Arena at the end of the season, although his final destination has yet to be confirmed.

Bristol were thought to be Haskell's most likely destination, but now The Rugby Paper claims Worcester, who are looking to replace David Denton after the Scotland international signed for Leicester Tigers, are the front-runners.

Warriors have been busy in the transfer market. Versatile back Scott van Breda has become the latest recruit after agreeing to join from Championship side Jersey Reds in the summer, while the club are understood to be looking to sign fly-halves Duncan Weir and Jono Lance.

Ulster prop Callum Black, Ospreys centre Ashley Beck, Edinburgh back row Cornell du Preez, Doncaster Knights scrum-half Michael Heaney and London Scottish hooker Isaac Miller have also decided to make the switch to Sixways.

Joining Denton through the exit door are Will Spencer (Leicester), Jackson Willison (Bath) and Huw Taylor (Dragons).

Gloucester are being linked with a number of South Africa internationals, the latest being lock Franco Mostert who is apparently being lined up to replace Jeremy Thrush.
