Albion have now moved past the 40-point mark to all but ensure a third successive season of top-flight football.
Hodgson was keen to praise Dorrans, who has struggled with injuries during the past 12 months.
He said: "It was a marvellous strike and Graham Dorrans deserves a lot of credit.
"After such a long period of time out, a season which has been interspersed with injuries, it has been a fine week for him.
"He did well against Blackburn, he was one of our better players against Manchester City, and he settles this game for us.
"We are delighted with him."
