No, I didn't see the match, but are you saying that he dived, and in the process nearly tripped the ref up?
Wouldn't be suprised.
The only thing Barnes did in his 90 minutes today was manage to claim for 3 penalties by going down clutching his face. Sadly, he was not touched anywhere near his face on any occasion. Oh and yes, I was there, this isn't judging by the radio commentary.
