Rob Gronkowski underwent season-ending back surgery in December but says he'll be ready for the New England Patriots' title defense.
The tight end told ESPN's Cari Champion he will "no doubt" be good to go for the 2017 season.
Gronk's December surgery to fix a herniated disc was the third on his back, dating back to his college days. The most recent back injury stemmed from a brutal hit by Seattle Seahawks safety Earl Thomas. The tight end previously missed time in 2016 with a hamstring injury and bruised lung.
