Portsmouth boss Adams unsure of Crouch 'handball'
The England international scored the opening goal in the 38th minute but appeared to handle the ball prior to the scoring act.
Adams said he wasn't sure what had happened and was loathe to get involved in such controversies.
"I didn't see it. It was a good counter-attack but apart from that...," Adams said.
"I don't get involved in controversy. I can't control these things because they are moments of luck and chance. I concentrate on working with the team and getting them organised."
