Even after adding wide receivers Jeremy Kerley and Rod Streater last week, the 49ers may be in the market for another wideout.
Former Patriots wide receiver KeShawn Martin visited the 49ers on Saturday, according to ESPN.
The 26-year-old Martin was cut by New England on Sept. 3.
Acquired by the Patriots from the Texans on Sept 17, 2015, Martin caught 24 passes for 269 yards and two touchdowns in 2015.
Selected in the fourth round of the 2012 NFL Draft by Houston, Martin caught a total of 38 passes for 416 yards and three touchdowns in his first three seasons.
