CBS Sports journalist Grant Wahl -- one of the most respected soccer reporters in the country -- died while covering the World Cup, his brother announced Friday. He was 48 years old. Grant was in Qatar when he passed and Eric Wahl believes foul play was involved, as he claims the reporter was receiving death threats over wearing a rainbow shirt in support of the LGBTQ+ community. Eric says Grant had zero health issues, explaining in a heartbreaking Instagram video, "I do not believe my brother just died. I believe he was killed." Grant Wahl was detained for nearly 30 minutes after World Cup security on Nov. 21, after he showed up to Ahmed bin Ali Stadium in Qatar for the United States' first tournament game against Wales.
