Carlo was so impressed with his opposite number's performance he handed Walker his mud-splattered shirt after the match and signed it: "To Leigh, all the best for the season."
Then things began to go wrong. Here's Leigh to explain all: "My mum threw the shirt in the washing machine when I got home on Saturday night because it was caked in mud.
"So Carlo's autograph has been washed out of his jersey - which is a real sickener."
Walker's mum, however, is refusing to take any of the blame. She insists that it is Carlo's fault: "I thought it might have been waterproof ink but it obviously wasn't," she said.
Rumours that Walker was planning to sell the shirt on ebay were unfounded (and completely made up!)....
