Gronk Flakes hitting breakfast tables

Pittsburgh-based PLB Sports has started selling two 14-ounce boxes of Gronk Flakes online for $10. The company says a portion of the proceeds will benefit the New England tight end's Gronk Nation Youth Foundation.

Photos had surfaced on Twitter during the week indicating that Gronk Flakes would be hitting the shelves before long.

When asked about the cereal, Gronkowski responded in typical Gronk fashion.

"If you want to be buff like me, you'll eat that stuff," Gronkowski told the Boston Herald's Jeff Howe.

Earlier in the week, the cereal company unveiled its "MariO's" brand in honor of the Buffalo Bills' Mario Williams. The defensive lineman is donating proceeds to benefit pediatric cancer patients at Roswell Park Cancer Institute.
