Exeter Chiefs made sure of the National League One runners-up spot behind Northampton but they left it late at Castle Park.

Chiefs were 10-0 in front with tries from scrum-half Clive Stuart-Smith and left wing Sean Marsden.

Despite falling behind Exeter rallied through right wing Josh Drauniniu.

Then deep into added time replacement Kevin Barrett crossed the line to score the all-important try that gave the Chiefs the vital bonus point.
