England centre Ollie Lawrence has been ruled out of their final Six Nations match against Ireland due to a hamstring injury, the Rugby Football Union (RFU) said on Monday.Lawrence, who had started each of England's last three games, sustained the injury during their 53-10 drubbing by France this weekend, which was England's third heaviest ever defeat and their biggest at home.Head coach Steve Borthwick named a 36-man squad to face Grand Slam-chasing Ireland in Dublin on Saturday, recalling George Ford after the flyhalf was left out of the France squad in favour of Owen Farrell and Marcus Smith.Leicester centre Guy Porter has been drafted in as cover for Lawrence, while Sale lock Jonny Hill returns to the national set-up to contest for a second-row slot.Harlequins prop Will Collier, who played for England in last year's Barbarians game, also earned a call-up.England are fourth in the Six Nations standings after two wins and two defeats, while Ireland are top and extended their 100 per cent record with a win over Scotland on Sunday.England squadForwardsOllie Chessum (Leicester Tigers, 9 caps)Dan Cole (Leicester Tigers, 99 caps)Will Collier (Harlequins, 2 caps)Ben Curry (Sale Sharks, 4 caps)Alex Dombrandt (Harlequins, 13 caps)Tom Dunn (Bath Rugby, 3 caps)Ben Earl (Saracens, 15 caps)Ellis Genge (Bristol Bears, 47 caps)Jamie George (Saracens, 76 caps)Jonny Hill (Sale Sharks, 19 caps)Nick Isiekwe (Saracens, 10 caps)Maro Itoje (Saracens, 66 caps)Lewis Ludlam (Northampton Saints, 18 caps)David Ribbans (Northampton Saints, 4 caps)Bevan Rodd (Sale Sharks, 2 caps)Kyle Sinckler (Bristol Bears, 60 caps)Mako Vunipola (Saracens, 78 caps)Jack Walker (Harlequins, 3 caps)Jack Willis (Toulouse, 9 caps)BacksHenry Arundell (London Irish, 6
