Manish Kaushik dealt a big blow to Shiva Thapa’s hopes, beating him in the national selection trials to book a berth in the Indian squad for the World Boxing Championships to be held in Ekaterinburg, Russia from September 7-21. Thapa had revived his career when he won bronze at the Asian Championships in April for his fourth medal from the meet. If he thought he had settled his rivalry with Kaushik when he defeated him in the final of 60kg at the India Open, it was not the case.
