Powell said: "It's a tough place to come, a decent team and we had the victory in our last game and we wanted to build on it.
"Obviously taking the lead, you want to try and see it out and try and take three points but I think it was a well-earned away point.
"It was quite a heated battle at times but of course it was definitely a penalty. They obviously got their equaliser, it was a little bit nip and tuck and they put us under pressure towards the end but our players stood up to it.
"It was a decent point and a decent way to start this quite a tough week for all Championship sides. But for us with two away games, we go away now to Huddersfield and then we've got a local derby next Saturday so a good start to what is quite a hectic week."
