The 49ers are signing wide receiver/kick returner Keshawn Martin, as freelance NFL reporter Rand Getlin tweets. Interestingly, it will be a two-year contract for Martin.

Last year, Martin averaged 11.2 yards per reception with New England, though that came on a limited sample size of 24 receptions. Prior to the 2015 season, Martin spent his first three seasons with the Texans and saw the field in every regular season contest from 2012-2014. For his career, Martin has averaged 25.2 yards per kick return and it will be interesting to see how Martin is split between offense and special teams in SF.

As of this writing, the 49ers also have Torrey Smith, Quinton Patton, Jeremy Kerley, Rod Streater, and Aaron Burbridge on the WR depth chart.
