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.

After a rough down year for the San Francisco 49ers last season, Kyle Shanahan's bunch is (understandably) looking for a major rebound to contention this fall. Such a rebound will likely require everyone in the 49ers' core to be on the same page and working as one.

San Francisco 49ers star tight end George Kittle took to social media to refute reports that he's skipping voluntary workouts because of a contract dispute. Kittle was not in Santa Clara on Tuesday for the first day of the 49ers' offseason slate.
