England's last four wickets could muster only 14 runs on the fourth morning of the third Test against India - leaving them with a first-innings lead of 207 at Eden Gardens.
The tourists were all out for 523, after overnight pair Matt Prior and Graeme Swann could add only a single between them to their existing seventh-wicket stand of 56.
England lost their first two wickets on Saturday in the space of seven balls.
Prior had driven the first for a single, only for Swann to then immediately become Pragyan Ojha's fourth victim - edging another attempted drive to slip.
Then Prior himself went to cut Zaheer Khan at the other end, and edged behind.
Steven Finn and James Anderson managed a boundary each, but the introduction of Ravichandran Ashwin for Ojha (four for 142) brought two wickets in two balls to conclude the innings.
Ashwin had previously conceded 183 runs for his one success - but after Anderson edged to slip and Monty Panesar went lbw first ball, despite an apparent inside-edge, the off-spinner had two more at no further cost.
