There are only two team sports represented in this years short list, one being Grand slam winning player of the tournament Lydiate, who is the only rugby union player nominated.
The Newport Gwent Dragons player fractured his ankle whilst playing against Edinburgh in the men of Gwent’s RaboDirect Pro 12, so he missed out on the Wales’ autumn test series.
