Lawrence Okoye 'to sign for San Francisco 49ers' British Olympic discus thrower Lawrence Okoye says he is to sign for the San Francisco 49ers as a free agent. The 21-year-old, who was 12th in the discus at London 2012, was not selected on the final day of the NFL draft. But he tweeted: "Proud to announce I will be signing with the @49ers!" Manchester-born Menelik Watson was drafted by Oakland in the second round while Tom Wort from Crawley has joined the Tennessee Titans, also as an undrafted free agent. Olympian Okoye's NFL ambitions Okoye, who stands at 6ft 6in and weighs 21st, turned down offers to play rugby union and was also accepted to study law at Oxford University. He initially said he intended to carry on with the discus and aim for the Rio Olympics in 2016. But he subsequently decided to switch to American football and impressed scouts at the Super Regional Combine despite having never played the sport. According to reports he will sign a three-year deal with the 49ers and will play in the defensive line. Former Florida State University star Watson, 24, who has only been playing for two years, was picked up by Oakland Raiders as the 10th player in the second round, the 42nd overall. Wort, a 22-year-old linebacker who moved to the United States aged 14, had been touted as a possible third-round pick on the final day but like Okoye, has been picked up as an undrafted free agent.
