Tyrone midfielder Brian Kennedy was sent off after 26 minutes of his side's Ulster Football Championship match against Derry in Omagh.
After winning a free, the 2021 All-Star kicked out at Derry's Gareth McKinless in what former Down footballer Marty Clarke called a "crazy moment".
"We went through different predictions for this game," Tyrone legend Peter Canavan told BBC Northern Ireland during their coverage of the game.
"None of us predicted that Gareth McKinless would end up marking Brian Kennedy. I don't think Brian Kennedy was expecting that.
"McKinless has been running all over the place. He's sweeping, he's bombing forward, and he's frustrated Brian Kennedy, culminating in that sending off. He lashed out at him."
Former Armagh footballer Oisín McConville thought the moment was "uncharacteristic for Brian Kennedy".
"Since he's come in, he's made that position his own," said McConville.
"He's workmanlike in everything he does. It's out of character for the Brian Kennedy we've seen over the last number of years."
Moments after Kennedy was sent off, Derry won a penalty which was converted by Shane McGuigan. Derry took a seven-point lead into half-time against the All-Ireland champions.
Tyrone also had Conor McKenna sent off in the second half. Derry went on to win the game by 11 points.
