Umpire Billy Bowden ruled Yuvraj caught behind off Stuart Clark on Thursday, a decision that failed to amuse the left-hander, who was yet to open his account in India's first innings.

Though the snickometer suggested a thin edge, Yuvraj lingered for a few seconds at the crease before finally departing.

The left-hander is expected to attend a hearing with Proctor later on Friday, and if found guilty might lose part of his match fee, media reports in Australia said.
