At the other end of the experience scale, Luke Charteris is named in the starting line-up and will make his 100th RaboDirect PRO12 appearance on Friday night.
The other change in the backs comes at scrum half where Wayne Evans starts in place of Joe Bedford.
There are two changes in the pack, Steve Jones replaces Sam Parry at hooker and Jevon Groves starts at lock ahead of Rob Sidoli who is fast approaching 2000 minutes of rugby this season, having played an incredible 1952 minutes for the Dragons already.
Pat Leach is named on the bench and could be in line to make his first appearance since breaking his hand in the match between these sides in the LV= Cup match at the Brewery Field in January.
