England prop Mako Vunipola will make an eagerly awaited return from injury for Saracens against Gloucester this Friday in the Aviva Premiership.
Vunipola has missed the start of England's defence of their Six Nations crown having been sidelined with a knee injury he sustained in December.
He sustained ligament damage in the Premiership clash with Sale and was left out of England's training squad ahead of their Six Nations clash with Italy a week on Sunday at Twickenham.
Eddie Jones will hope he gets through Friday nights clash at Kingsholm, with a view to have the ball-carrying front row back for their crucial games with Scotland and then Ireland on the last day of the Championship.
Having spent nine weeks on the sideline he will have to prove his fitness to fight his way back into contention for a starting role in the England team.
Saracens are five points off league leaders Wasps and coming off the back of their 24-18 defeat at Worcester, Mark McCall will hope his charges can get back to winning ways away after two games without a win.
Gloucester meanwhile will hope to put further distance between themselves and the relegation battle going on below them.
