Olympic and world champion javelin throw star Neeraj Chopra has opted out of this Sunday's Paris Diamond League, citing the adductor niggle that has been troubling him for the past couple of months, according to a report. Speaking to 'ESPN', Chopra said he is focusing on training and strengthening his blocking leg. "I need to strengthen my blocking leg when I throw because that's when my groin gets pulled. We're working on that to see how we can reduce the impact on the groin and control the pressure on it," he said, explaining the issue for which he will consult "different doctors" after the Paris Games.
