Gaganjeet Bhullar struggled on the moving day and slipped down considerably as he carded a three-over 75 with three bogeys and a double bogey to be tied 18th after being fifth overnight at the M2M Russian Open.
Bhullar is now three-under 213 and will need a very good final round to get into the top-10.
Meanwhile SSP Chowrasia, who made the cut on the line, improved his position with an even par 72 and he is now two-over 218 in tied 52nd place.
At the top, Scotland's Peter Whiteford goes head to head with Englishman David Horsey in the final round.
Whiteford, 33, fired a six-under par 66 in the third round at Tseleevo Golf and Polo Club to catch up with Horsey, who signed for a 70, and at 13 under.
The pair are four shots clear of Scotland's Scott Jamieson (69), Italian Andrea Pavan (64) and Belgian Thomas Pieters (72).
Whiteford, who is 190th in The Race to Dubai having only made four cuts all season, had a brilliant front nine, notching five birdies and an eagle against one dropped shot, then played the back nine in level par.
