Summer signing Cook, who has bagged sixteen goals in his first season in the EFL, was given a straight red card by referee Brett Huxtable with just six-minutes on the clock following a mid-air collision with Nathaniel Knight-Percival, the two players competing to win a header.
The former Tranmere striker was adamant it was just a coming together, but the Devon-based referee believed he had spotted an elbow with the 28-year-old given his marching orders. Keates, who was proud as his team went on to secure their first win in six league outings, hasn't ruled out appealing the decision, with the boss believing the call was harsh.
Speaking via the Express & Star, Dean said; "I have the seen footage from our analyst, zooming out so I can see as much of the pitch as I can. The arm’s up but there’s no contact with the arm. It’s the side of Cooky's body, his torso, that catches him as he jumps across him.
"So I will have a little closer look at the club’s footage and maybe what Sky have got from the highlights and we will go from there. It’s a little bit grainy, our footage, but it doesn’t look like he’s caught him. But I’ll have a clearer picture when I see close-up footage."
