Martin remains unsigned as an unrestricted free agent, Matt Kawahara of The San Francisco Chronicle reports.
Martin stayed healthy throughout 2018 and re-established himself as a competent NFL player, but his 172-723-4 rushing line (4.2 YPC) and 18-116-0 receiving line don't exactly demand a major contractual commitment. He figures to eventually latch on somewhere, likely needing to earn a roster spot ahead of his age-30 season. Oakland could be an option if Marshawn Lynch retires again, though the team already signed Isaiah Crowell as a backfield option for early downs. There's little-to-no chance of Martin regaining the top form he displayed in 2012 and 2015.
