Both players have already featured in the first team this season, with Clark playing three times in all competitions and Hayhurst making his debut in last week's 2-2 draw against Charlton.
The pair have been regular starters in the club's double-winning youth team and will be in the squad for the final day trip to Bournemouth on Saturday.
Clark is a central midfielder known for being a free-kick specialist, while Hayhurst, who has overcome two leg breaks, is an energetic winger.
