You likely were impressed with George Kittle's sophomore season with the 49ers, in which he set the NFL single-season record for most receiving yards by a tight end.
But perhaps you'll be even more impressed upon learning Kittle set that record after fracturing his rib cartilage midway through the season.
Kittle said he suffered the injury on the third play of the 49ers' Week 9 win over the Raiders, in which he caught four passes for 108 yards and a touchdown. One of those receptions was with one hand for a 71-yard gain.
