Luke Cowan-Dickie celebrates signing a new deal until 2015 at Exeter Chiefs by starting against Ospreys in tomorrow's LV= Cup clash at Sandy Park (1700).

The Cornish prop is one of three Chiefs changes to the side that won their cup opener 42-15 at London Welsh.

Hoani Tui returns to the front row while Jack Yeandle makes his first-ever senior start for the Chiefs.

Exeter will head into the game full of confidence following their win at Welsh, where young, two-try scoring full back Jack Nowell led the way with a man-of-the-match display and there were also tries for Nic Sestaret (2) Will Carrick-Smith and Mark Foster.

All four try-scorers are retained in an unchanged although Chiefs - who last season overcame the Ospreys 35-9 in the same competition - have opted for a reshuffle with Sestaret moving back into the centre alongside Sam Hill; Nowell reverts to wing and Myles Dorrian to 15.
