Dallas Cowboys Jersey Not Identified Correctly?

[short84]

As a collector of Dallas Cowboys' jerseys, I spend quite a bit of time looking at the Steiner Website, especially their Cowboys-Steiner auctions. I have been very fortunate to pick up some good deals. There is currently a game used white Roy Williams #11 jersey listed as follows: Roy Williams #11 Cowboys at Redskins 11-22-2009 Game Used White Jersey. The picture of the jersey shows a rather significant grass stain on the back. Only problem is that the Cowboys played the Redskins at home in Cowboys Stadium on November 22, 2009 and this stadium has artifical turf, not real grass. The Cowboys played the Redskins again on December 27, 2009 in Washington. They wore their blue jerseys in that game, not the white ones. How could a jersey worn during a game played on artifical turf obtain a rather large grass stain unless it was not identified correctly? Seems like there are 2 significant errors -- the Cowboys played at home (not AT the Redskins) 11-22-09 and they played on artifical turf (not grass).

A quick check of getty images turned up what appears to be a photomatch for the jersey to the week before (11/15/2009) vs. the Green Bay Packers.

The error is unfortunate but a great photomatch for any Cowboys/Williams fans.

Great match -- thank you.
