The Jacksonville Jaguars announced Friday that they have signed running back Jonathan Grimes and waived running back Tyler Gaffney.
Gaffney, 26, had spent the last two seasons with the New England Patriots before latching on with the Jaguars. He's yet to take a regular-season snap since he was selected in the sixth round of the 2014 draft.
Grimes, meanwhile, spent the last four seasons as a seldom-used rotational piece in the Houston Texans backfield.
During that span, the undrafted free agent out of William & Mary managed 139 carries for 613 yards and two touchdowns.
