Kittle is entering the final year of his contract, which holds a $22 million salary cap number for the Niners. Per OverTheCap, his contract's $15 million average annual value places him fourth at the tight end position, with Arizona Cardinals star Trey McBride leading the pack with his market-setting four-year, $76 million deal ($19 million AAV).

San Francisco 49ers star tight end George Kittle took to social media to refute reports that his absence from voluntary workouts was contract-related.

The 49ers' internal culture, even above the talent, has to be so strong, after all.
