EXPERIENCED lock Donncha O'Callaghan will skipper Worcester Warriors in tomorrow's Aviva Premiership clash with Saracens at Sixways (3pm).

Wing Perry Humphreys, O’Callaghan and number eight Alafoti Fa'osiliva have all come into the starting line-up.

Back row Chris Vui is set for his Premiership debut after impressing in last weekend’s win at Cardiff Blues in the Anglo-Welsh Cup.

There is no place for back row Dewald Potgieter, who led the side against the Blues, but picked up an ankle knock at the start of the week.

In the replacements, new signing Ryan Grant could make his debut, while Ryan Lamb returns from a lengthy injury lay-off, having not featured since October. Fijian Tevita Cavubati and Marco Mama also return to the squad.

Experienced duo Cooper Vuna and Phil Dowson have not made the squad.

Brad Barritt returns to captain Saracens after serving a three-week suspension. 

Barritt starts at inside centre to partner the in-form Nick Tompkins in Sarries midfield, with Chris Ashton, Mike Ellery and Matt Gallagher  starting in the back-three.

At half-back, Alex Lozowski starts at fly-half after returning from England camp to partner scrum-half Richard Wigglesworth.

Up front, Richard Barrington, Schalk Brits and Petrus Du Plessis are named in the front-row with Michael Rhodes and Jim Hamilton packing down at lock.

In the back row, Will Fraser continues in the side at blindside flanker joining Schalk Burger and Jackson Wray.

On the bench, Jared Saunders, Titi Lamositele and Juan Figallo are the front-row replacements, with Mark Flanagan and Kelly Brown the other forward options.

Ben Spencer is the scrum-half cover with youngster Max Malins coming into the matchday 23 on the back of a fine performance for England U20 last weekend.

Marcelo Bosch will wear the number 23 jersey.
