From SB Nation.com: Griggs landed a well-timed uppercut that cut Lashley badly next to his left eye. The first round ended with Lashley pouring blood but safely winning the round.
In the second Lashley got another takedown but looked to be getting tired. He spent more time in side control and eventually passed to mount but he was unable to do much with the position. The referee decided to stop the fight to allow the doctor to check the cut, which had begun bleeding badly again, and made the odd decision to not restart them in mount. It was the beginning of the end as Lashley shot in poorly and got hit several times by Griggs as the round ended including several shots that appeared to be illegal and to the back of the head. When the round ended Lashley did not get off the ground and chose not to continue.
Lets see ... Griggs dealt with Lashley's ground game, delivered some strikes to the inexperienced fighter and wore the big man down.
Basically, it went exactly how he planned it.
