Last year I noticed that 2009 Topps Football #85 Tony Gonzalez had the very same error. Instead of HK, Gonzo had the GU (Gene Upshaw) memorial patch worn league wide in 2008, when he was with Kansas City. What Topps did not do when painting him in Atlanta Falcons colors prior to their 2009 FB release, they failed to edit the GU patch off his jersey.
2009 Topps #85 (poor paint job by Topps not to edit off GU patch)
2008 Season (League wore "GU" patch for Week 1 only) Coincidentally, this was the Tom Brady leg injury game too.
There you have it .
