Just another layer to an already venomous border battle rivalry!

Yup, that's Favre’s No. 4 VIKINGS jersey, VIKINGS pants and the inactive sheet from Favre’s final game in the NFL (played with the VIKINGS).

That outta get Packers fans riled up!

It’s worth noting that the Hall of Fame chooses the memorabilia that goes in each locker.  Plus, it's worth pointing out that statistically 2009 was his best season as a pro - even if it was while he was wearing purple n' gold!

Also, Favre was wearing a Vikings jersey when he broke Jim Marshall’s record for consecutive games played.  

The Vikings happened to see ESPN’s tweet and responded with a simple wink:

Favre was inducted into the Packers Hall of Fame last summer and had his No. 4 retired in front of a sold-out crowd at Lambeau Field... which I have to admit, as a Vikings fan was pretty cool to watch.  The man could play!

That Brett Favre though... such a SAVAGE!
