NFL reporter Dianna Russini is standing by her reporting about George Kittle's contract dispute with the San Francisco 49ers, despite the All-Pro tight end publicly refuting what she's said. Kittle and the Niners are currently negotiating a new deal for the 31-year-old as he's entering the final year of his contract.

The Athletic's Dianna Russini reported that, according to sources, tight end George Kittle's absence from the start of the San Francisco 49ers' offseason program is contract-related.
