The centre-back saw red just 35 minutes into the 1-0 defeat at Valley Parade for what referee Darren Bond deemed as an elbow in the face of Bradford's James Meredith.
But despite the Gulls decision not to appeal the three-match ban, Saah insists it was an accident.
"I have caught him, but I didn't mean to," he told the Western Morning News. "It was an accident. It was never meant to happen. I feel like I'm getting punished for doing something I never even intended to do, which is hard to take.
"As soon as I saw the replay, even though I still think it looked worse than it was, I knew there was no point appealing."
Saah, who had been the stand-in captain in the absence of skipper Lee Mansell through a red card of his own, will miss the Plainmoor clashes with Northampton and Exeter and the trip to Home Park to face Plymouth on Boxing Day.
