Picture of the day: Two Silvas, a Hughes and a Penn

Zuffa is holding its annual Fighters' Summit in Las Vegas this week, and Strikeforce and UFC fighters have been tweeting pictures from the sessions that cover everything from injuries to using social media. Bantamweight Eddie Wineland snapped this picture of several MMA legends, just sitting and listening to presentations.

That's UFC middleweight champion and Yahoo! Sports pound-for-pound king Anderson Silva and former PRIDE champion Wanderlei Silva in the foreground. Sitting in the table in front of them is UFC Hall-of-Famer Matt Hughes, and who appears to be former welterweight and lightweight champ B.J. Penn. Between them, they have five major championships and a record of 122-29-3.
