Welsh offend at the breakdown and Mumm immediately points to the posts. Slade from 30m out and 15m in from the left touchline. No problems! 3-5

Restart is cleared to touch by Welsh. Chiefs LO about 30m out.

Try London Welsh! Nathan Trevett dives over for a short range try. A costly mistake for the chiefs at that last LO. No extras. 0-5

Chiefs lose the LO and Welsh are on the offensive again. They think they have scored. Ref going upstairs.

Chiefs cannot gather cleanly and Welsh attack. Chiefs defence holds. Welsh maintain possession and finally get forced into touch.

Welsh to start the game kicking towards the South-West stand.

KO 3pm. Stay tuned for live updates

The Chiefs are expected to extend their winning streak to four games against the Exiles, who have conceded 726 points in 16 successive Premiership games defeats. The in-form Henry Slade continues at fly-half after kicking 11 points in last weekend’s win over Bath, while Australia international Dean Mumm skippers the side from the second row. London Welsh have made 10 changes to the team that shipped 50 points at home to London Irish in round 16. Seven of those come in the pack, with No 8 Opeti Fonua the only survivor, while Tristan Roberts starts at fly-half.
