AS Roma defender Evan Ndicka has been cleared to resume sporting activity after undergoing a series of tests, the Serie A club said on Tuesday, days after the 24-year-old collapsed on the pitch during their match against Udinese with a collapsed lung. The Paris-born player, who represents the Ivory Coast, was carried off on a stretcher after falling backwards onto the pitch in the 18th minute with the game in Udine later abandoned at 1-1. 'Ndicka underwent a series of cardiologic and third level pulmonary tests,' Roma said in a statement.
