Ian Heinisch thinks he gave Kelvin Gastelum too much respect in their first outing and vows not to make that mistake again. In the biggest spot of his career, Heinisch (14-4 MMA, 3-3 UFC) dropped a unanimous decision to former interim title challenger Gastelum at UFC 258 in February. He was outwrestled over the course of three rounds in a gritty affair. Heinisch admits he focused a little too much on the potential dangers the heavy-handed Gastelum can bring, which didn’t allow him to generate much offense. So going into his fight with Nassourdine Imamov (9-3 MMA, 1-1 UFC) at UFC on ESPN 27 on July 24, the former LFA middleweight champion is only worrying about what he brings to the table. “I feel like I over-assessed Kelvin Gastelum in my last fight,” Heinisch told MMA Junkie Radio.
