Team news and statistics ahead of Saturday's Gallagher Premiership Play-Off semi-finals.
Exeter v Northampton
Exeter have made one change to the side that thrashed Northampton last weekend by naming Tom O'Flaherty on the left wing instead of Olly Woodburn. Dylan Hartley's knee injury means he finishes Northampton's season without having played since mid-December.
James Fish fills Saints' crisis position at hooker after Reece Marshall was ruled out by a hamstring injury with on-loan Coventry forward Darren Dawidiuk covering from the bench. Francois van Wyk and Ehren Painter also start in an overhauled front row.
