Saw this on ESPN from Darren Rovell:
No, the Houston Texans did not win the 1961 AFC Championship, but that's what T-shirts produced by clothing chain Old Navy said.
After word circulated on the Internet about the mistake, the company will be pulling the items from its website and from stores, a company spokesperson told ESPN.com.
"The NFL clothing sold in our Old Navy stores is created by a third party sports licensing company," said Edie Kissko, a spokesperson for Gap Inc., which owns the Old Navy brand, in a statement. "It is our intention to always provide the best merchandise to our customers and NFL fans. We apologize for this error and are removing the T-shirts."
It was the Houston Oilers, not the Texans of course, that won the 1961 title -- and it was an AFL title. The AFC didn't come into existence until the 1970 merger and several decades later the Oilers moved from Texas to Tennessee and became the Titans. The Texans were an expansion franchise that came into the league in 2002.
The shirt is still for sale. It's $19.50 plus $7 shipping (free shipping for orders $50 or greater).
