Heneghan signed with San Francisco as an undrafted free agent Monday.

Heneghan participated in the 49ers' local pro day one week prior to this year's NFL draft. Evidently, San Francisco liked enough of what they saw from Heneghan to bring him into the fold this offseason. The chances of Heneghan making the final roster remain a long shot behind Jimmy Garoppolo and C.J. Beathard.
