The San Francisco 49ers signed tight end George Kittle to a four-year, $76.4 million contract extension, a source familiar with the agreement told UPI on Tuesday.

The 49ers disappointingly finished last in the NFC West with a 6-11 record, but Kittle was one of the team's few bright spots. He put forth a strong season with 78 catches for 1,106 yards and eight touchdowns across 15 games on his way to earning his sixth career Pro Bowl selection and second-team All-Pro honors.
