The San Francisco 49ers worked out former Buffalo Bills tight end Chris Gragg, according to NFL Draft Diamonds.

The Bills made Gragg a seventh-round draft pick out of Arkansas in 2013. He has registered 24 receptions for 251 yards with two touchdowns in three NFL seasons (2013-15). A torn ACL during a preseason game forced Gragg to miss the entire 2016 season. He was released the following March.

Gragg signed on with the New York Jets on July 28, 2017, but an ankle injury landed him on injured reserve before the start of the regular season.
