Exeter Chiefs roared back from 17-3 down to stun Worcester Warriors and claim a thrilling Premiership triumph on Sunday.

The Chiefs were indebted to Harry Williams as the prop’s late converted try sealed a dramatic 24-20 victory at Sixways.

A very different story appeared to be unfolding when Perry Humphreys touched down twice in the first half for the hosts, with Duncan Weir adding the extras both times and kicking a penalty.

But the Chiefs, beaten in the final last season after topping the table, cut the deficit courtesy of Jack Maunder’s score.

And the second half belonged to the visitors, who ramped up the pressure when Matt Kvesic dotted down against his former club.

Another Weir penalty looked to have earned the Warriors some breathing space but Williams had other ideas and powered over to win it for his side.
