Mark McCall is looking forward to seeing Jack Singleton back in black after the former Saracens academy prospect re-joined the club on a three-year deal from Worcester Warriors.

The 22-year-old will arrive at Allianz Park in the summer having played for the academy side until departing in 2014 for Warriors, where he made his Premiership debut in 2016.

Singleton went on to tour Argentina and South Africa with the senior England side, as well as playing in an uncapped match against the Barbarians, but is yet to win a full cap.

And Saracens director of rugby McCall hailed the return of the hooker, who is expected to replace Christopher Tolofua in the squad - with the France international set to leave for Toulon.

“We're pleased to have signed a player of Jack's quality; someone who knows the club well, having been in our academy,” said McCall.

“He has significantly progressed his rugby with Worcester and we are excited to see what more is to come.”

Speaking about his return to Saracens, Singleton said: “It's a homecoming for me. It's the club I supported from a young age and used to watch regularly.

“I'd like to thank Worcester for an incredible five years. They gave me the chance to progress as a player and have helped me develop immensely in that period.”

Meanwhile, McCall has named the Saracens team for their clash against Wasps at the Ricoh Arena on Saturday, with eight academy graduates included in the starting XV.

Seven of the octet featured from the start in last weekend’s Heineken Champions Cup semi-final win over Munster with Nick Tompkins coming on at half-time.

The centre is the only change to the backline that began the game in Coventry. In the pack, the front five remains the same while there is just a single alteration to the back row.

Calum Clark comes in at openside flanker while Mike Rhodes and Billy Vunipola stay at six and eight respectively, with centre Dom Morris set to make his Premiership debut from the bench.
