The Irishman, who has come in for criticism in recent weeks for his own robust approach to the game, shrugged off a two-footed lunge which resulted in Thistle's Jordan McMillan receiving the first yellow card of the afternoon.
St Mirren full-back Jason Naismith followed the former Rangers defender into the referee's book after a challenge on Kallum Higginbotham which resulted in the Englishman being stretchered from the field of play with a serious knee injury.
But it was the foul on Goodwin which had the home fans furious and Lennon was quick to praise the midfielder for his attitude which helped calm the situation.
"Jim didn't make anything of it, that shows you the character of the man. He's man enough to take it," he said.
"He does give it out himself, but that's the nature of the game. Jim loves the physicality of it, but unfortunately the laws of the game and the way the game has gone means they're protecting players, but I thought he did terrifically well today.
"He's such an important player for us is and I can understand why opposing managers and fans want Jim Goodwin not in our team because it weakens us.
"He's a very valuable part of the team and when Jim keeps his concentration levels like that, and when he keeps himself on the right side of the laws of the game, he's a very, very influential player for St Mirren Football Club."
But McMillan rubbished suggestions he should have seen red for the tackle, even challenging the decision by John Beaton to brandish a yellow.
"The two of us went for the ball," he said. "I said to the ref, both of us were committed and going for the ball but obviously Jim screamed louder than me and he got the foul.
"But to be fair he got up and got on with it, so I took the booking even though I think it was more of a 50/50."
Meanwhile, Thistle boss Alan Archibald praised his players for the display they served up despite the driving rain and slippery under-foot conditions.
"For a manager you don't want to watch a game that's going end to end," he said.
"I know it might be good for the fans, but it got a bit wide open and I thought the conditions made it like that.
"It's tight down there, you don't know what's going to happen with results. It probably was a fair result."
