Origin prop Dunamis Lui has been dropped for a second time in three weeks by Raiders coach Ricky Stuart, to accommodate the return of Joseph Tapine from an ankle injury. Lui is part of Stuart's extended bench for Friday's crunch clash with the ladder-leading Penrith Panthers, but is set to line up for the club's NSW Cup side as he looks to build a fitness base which can handle this year's NRL rule changes. Tapine missed last weekend's win over Gold Coast after going down in the Warriors game a week prior, but has been named to retake his place at lock. Ryan Sutton started in the number 13 jersey last week, but will start at prop on Friday after continuing his hyper-productive start to the season. For Lui, who made his Queensland debut last year and subsequently endured a shorter preseason, adjusting to the NRL rule tweaks is taking longer than expected.
