Leicester Tigers colleague Greig Tonks is named among the replacements for the decisive Pool B encounter in the IRB Toshiba Junior World Championship.
After kicking off with a 43- win over Japan, England make eight changes to the team that started the 30-7 win over Scotland, with captain Calum Clark returning after a knee injury.
Samoa, ranked seventh in the world at this level, have also chalked up wins over Japan (29-22) and Scotland (17-14).
A win would put second seeds England into the semi-finals against the winner of tomorrow's South Africa versus France game in Osaka.
