Yuvraj, who had a forgettable 15-run outing in Punjab's embarrassing 137-run loss to Railways in the quarterfinals, gave his urine sample as part of a routine procedure an hour after the match.
Yuvraj gave his sample more than one hour after the match as most of the members of both the teams had left by then.
Before Yuvraj, Railways skipper Mahesh Rawat, who scored a century today, gave his sample along with pacer Anureet Singh.
