The San Francisco 49ers have reportedly added some depth to their wide receiver and returner depth chart. NFL Network reporter Rand Getlin tweeted that the 49ers have signed Keshawn Martin to a two-year contract. The 49ers worked out Martin a couple weeks ago.

Martin started his career with the Houston Texans as a fourth round pick in 2012. After three seasons, the Texans traded Martin and a sixth round pick to the New England Patriots for a fifth round pick. In 2015, Martin appeared in nine games, catching 24 passes for 269 yards and two touchdowns. He also had eight punt returns for 92 yards, and ten kickoff returns for 257 yards.

The 49ers wide receiver depth chart is weak, to say the least. Torrey Smith is their de facto No. 1, while Jeremy Kerley currently leads the team with 12 receptions for 114 yards. In returning, Kerley leads the team with three punt returns for 31 yards. On kickoff returns, they are averaging 18.4 yards per return, which is good for No. 24 in the NFL.
