Croft and Lawes train with England
Tom Croft and Courtney Lawes have been joined in England's training squad ahead of Sunday's RBS 6 Nations showdown with Scotland by Harlequins pair Joe Marler and Chris Robshaw.
Croft and Lawes, whose return to the England camp was confirmed on Monday, are in contention for Calcutta Cup selection after overcoming injuries.
Marler provides additional front-row cover for England, while Robshaw comes into the camp in place of Joe Worsley, who is receiving treatment at Wasps for knee and hand injuries.
Wasps centre Riki Flutey is also back at the club to receive treatment for a dead leg.
