Sturrock, who was assisted by former Argyle and Ipswich striker Paul Mariner, said: "We will have a look at the video and see if Darcy deserved a straight red card. If not we will lodge an appeal but first we will look at the tape.
"Overall I don't know at this stage whether it was a point gained or two dropped.
"What I do know is that we played with confidence in the first half and when we were a goal up but once we conceded that confidence seemed to be sucked out of us."
Ipswich boss Roy Keane, whose side remain at the bottom of the table and without a league win, praised the defending of the home side.
He said: "I have maybe been quick to have a go at our players for not hitting the target.
"I think it's important I give Plymouth credit today, to be fair, their defenders defended really well, you only have to look at Quinn's chance and the defender running back and clearing off the line.
"I guess when you go one down away from home, particularly with the ball taking ages to come back in when it goes out of play, I suppose we have got to be contented with a draw.
"The encouraging thing for me as a manager is that we are creating chances."
