Jake Hager won his second MMA bout in impressive fashion on Saturday night. Afterwards, Hager (2-0) was booed by the crowd for holding an arm triangle for several seconds after his opponent tapped.
“It was a quick win for Hager, who submitted his opponent with an arm-triangle after a little over three minutes of action. However, he kept the hold a few seconds after the tap, which was taken as a very bad sign of sportsmanship.”
