Williams is taking part in The Toughest Trade
Who has played 91 times for Wales and the Lions, scoring 60 tries? Who scored 0-4 for Donegal club Glenswilly in a challenge match against St. Mary's, Convoy on Thursday night?
You would be surprised to find out that the answer is the same to each question. Shane Williams swapped an oval ball, for the round one as he took part on The Toughest Trade.
Williams swapped Wales for the hills of Donegal, to take part in the series. All-Ireland winner Michael Murphy is to swap places with the 39-year-old, and spend a week with Top 14 giants Clermont Auvergne.
The winger played at full-forward for the three-time Donegal champions in blizzard conditions in Convoy.
Williams follows in the footsteps of former England international David Bentley and NFL wide receiver Roberto Wallace, who have swapped codes for the television show. The duo played in recent years for Armagh's Crossmaglen Rangers and Mayo's Breaffy.
The Wales winger scored 0-4, and impressed from the dead ball in tough conditions in Donegal.
Williams' performance will be broadcast later this year on The Toughest Trade.
