After being bowled out out for 191 to give India a huge 330-run first-innings lead, England staged a fightback through skipper Alastair Cook's unbeaten 74, which took them to 111 for no loss at close on day three.
"It was a shocker to lose wickets quickly and was disappointing. As a professional you have to look ahead and take positives. The way (Nick) Compton and Cookie (Alastair Cook) went about their task this afternoon was fantastic. We are behind but are still in the game," said Prior.
Prior top-scored with 48 in England's first innings.
India made 521 for eight declared in their first essay.
"We are honest enough to admit we did not get that right. We knew the wicket was going to turn a bit. I think we got a little bit ahead of ourselves and panicked a bit.
"(In the) second innings we were a lot more calm, led by Cookie and Compton, the way they batted. May be it's turning a bit, bouncing a bit, but you can bat with time out (there)," Prior added.

Though the team was shot out for under 200 with Pragyan Ojha taking five wickets, Prior said it was better to look ahead.
"There's no point in crying over spilled milk, you have to move on. We are still in this game though we are behind as 111 for no loss sums up the turnaround. That's what we would be looking at," he insisted.
Prior said that the wicket was behaving differently on different days.
"Wicket is certainly turning, you look at day 1 wicket and day 2 wicket - they were different. That's not an excuse at all. We were prepared for it. We have to execute our plans well." More
