Peter Betham and Jack Roberts form a new centre partnership for Leicester Tigers as they travel to league leaders Saracens in Round 7 of the Aviva Premiership season on Saturday.

Australia international Betham has played a part in every game so far this season, while Roberts makes his first start against the defending Premiership champions.
 
Mathew Tait reverts to full-back after injury to Telusa Veainu, with Roberts coming in for the unfortunate Matt Toomua who has had surgery on the knee injury picked up in his home debut last weekend.
 
In the forward pack, Graham Kitchener comes in to replace Dom Barrow who took a head knock in the win over Racing 92 in the European Champions Cup last weekend.
 
Ellis Genge and Luke Hamilton return to the matchday 23 and there is also a place among the replacements for George Catchpole.
