Scrum half Jonny Arr has been forced out of the sell out Guinness Premiership derby with Gloucester Rugby after the Worcester Warriors star failed a late fitness test.
Arr is now replaced in the starting line-up by Louis Silver, who made his league debut off the bench in the recent game with Leeds Carnegie, and Ollie Frost is named on the replacements bench.
