Middlesex Cricket has announced that England batsman Mark Stoneman will join the Club on loan.
Looking to get some quality match practice ahead of joining the Indian in Durham on Thursday, Ashwin did more than enough with 58 overs under his belt and a match haul of 7 for 127.
The Indian off-spinner became the first specialist slow bowler in last 11 years to open the bowling in an English county game after Jeetan Patel in the year 2010.
Ashwin, who is on a break in the UK like the rest of his India teammates after the World Test Championship final, has played for Nottinghamshire and Worcestershire in the past.
The 28-year-old sustained the injury after slipping in his socks while walking in the dressing room following Surrey's County Championship match against Middlesex at the Oval.
