Saracens prop Tom Mercey has been called up to the England squad for the start of the Six Nations.

The 21-year-old was promoted to the squad after an injury to Tim Payne. Mercey came on during England Saxons' 66-0 win over Portugal at Edgeley Park on Friday night.

Meanwhile, Steve Borthwick retains the captaincy for the opening Six Nations game on Saturday against Italy.
