[HIGHLIGHTS] Jacobs skips the challenge to Kerley of Rabat, 'it's just postponed'

Olympic champion is treated in Monaco for sciatica. Skip the season opener of Marcel Jacobs, the Olympic champion of the 100.

Jacobs is in Munich, where he underwent his first treatment with Professor Hans Mueller Wohlfahrt, former doctor of Bayern Munich and Usain Bolt, and who had followed him in the past. "It's not an injury - explains the Olympic champ - it's just the result of a false support, which however prevents me from competing in Morocco," he says.
