O'Driscoll, however, thought that Thompson had not touched Matthew Mills in the incident which led to his sending-off but that he did think that Thompson had landed a punch on Mills which earned him only a yellow card 20 minutes earlier.
"I didn't think Steve Thompson touched Matthew Mills at all for his second booking.
"But in the previous incident when they were both booked I thought he threw a punch.
On the draw which took Rovers off the foot of the table, O'Driscoll commented: "We kept possession of the ball well and competed well against arguably the form team of the league.
"However, I think we just missed that killer touch."
