Spurr will sit out Saturday's clash with Derby at Hillsborough after his dismissal at Norwich last week, and Buxton, who plys his trade at right-back, is a contender to make the switch.
"I'm right-footed really, but I can use my left," Buxton told The Star.
"It's more of a challenge playing on the left. Positionally, it's a bit different; as a right-back you get used to playing against left-footed players who want to go down the line.
"We'll have to wait and see what the manager is going to do. If I'm playing, whether it's right-back or left-back, I'll just do the best I can."
