Both players were taken off as precautionary measures during the 3-0 victory at Brentford on Saturday.
"Guly came off and was feeling his leg. It was a little bit tight," manager Nigel Adkins told the club`s official website. "Dan got a whack on his hip so we took him off too."
Adkins could make changes for a second game in the space of three days, with Danny Butterfield, Ryan Dickson and Jonathan Forte available for recalls.
Victory at Home Park would effectively secure automatic promotion for Saints as they would go into the final game of the season three points ahead of third-placed Huddersfield with a far superior goal difference.
