The former West Ham United and Aston Villa man won the ball in a challenge late in the 1-1 draw but sent Cronin sprawling with a strong follow-through which prompted criticism from some of the Quakes camp.
But Cronin says it was simply part of the game and has no qualms about the physicality imposed by Reo-Coker.
"Me flying in the air you don't see often, but ... nine times out of 10, that doesn't happen," Cronin said.
"[Typically,] we both just go in, the ball goes elsewhere and we just bump into each other a little bit. His intent wasn't to clean me out or anything.
"He was going for the ball. I was going for the ball. He came through me a little bit extra, but it's fine by me."
