Burnley can secure promotion if they record a better result than Derby County manage against Huddersfield Town, but Dyche is wary of the threat posed by a team which has won its last three matches.
"All the games have been huge this season," the Clarets boss told reporters. "I don't overthink each one as it comes, I just look at the next challenge and that's Middlesbrough.
"They're a good side that has probably underachieved, looking at their squad on paper.
"Their recent form has been very good and we can't underestimate that."
Burnely are currently 11 points clear of Derby, who occupy third spot in the Championship.
