Patrick Willis retired from professional football in March, turning plenty of heads in the NFL world.
A contingent of 49ers fans surmised that Willis would return to the game, especially after fellow insider linebacker Chris Borland followed suit and retired a week later.
But Willis, who has since bought into the tech industry, put those rumors to rest on Tuesday.

Willis was asked on Twitter Tuesday whether or not he thought he would "get that urge" once training camp and the preseason start.
His response: "No sir! I've made my decision."
Willis, 30, played eight NFL seasons for the 49ers and was named to the Pro Bowl in each of his first seven seasons. The five-time All-Pro's 732 career tackles ranks first in 49ers history, 11 more than Hall-of-Famer Ronnie Lott's 721.
