London - Wales players Alun Wyn Jones, Dan Biggar, Scott Williams and the uncapped Gareth Anscombe have all signed central contracts, the Welsh Rugby Union (WRU) have announced on Wednesday.
Ospreys team-mates Jones and Biggar, Scarlets centre Williams and Cardiff Blues flyhalf Anscombe follow Rhys Webb in signing a National Dual Contract, taking the total number of Welsh players on central contracts to 12.
"Alun Wyn, Dan, Scott and Gareth represent a cross-section of experience, but each one of them is a player of proven talent," said Wales head coach Warren Gatland in a statement on the WRU website.
