Richards will be starting at the heart of the defence, looking to regain full fitness. He had a truncated pre-season, last featuring in the 2-1 win against Watford, as he helped the United States win the CONCACAF Nations League in June.
Rak-Sakyi has been in and around the first-team through the entirety of pre-season, featuring off the bench on multiple occasions and scoring against Brondby.
The duo will have a chance to impress in their first competitive outing of the new campaign, as will new signing Chris Francis and two new trialists.
Jack Wells-Morrison continues his duty as skipper and will be partnered in midfield by Dylan Reid. Franco Umeh and Ademola Ola-Adebomi will join Rak-Sakyi to form a three-pronged attack.
