If the 49ers and Seahawks are not trolling fans at this point, I'd be at least a little bit surprised. The NFL released their daily transaction report, and the 49ers claimed wide receiver Charly Martin from the Seahawks. This move comes two days after the Seahawks claimed long snapper/tight end Kyle Nelson from the 49ers. I'm sure there are legitimate reasons for these moves, but once in a while I like to think the two teams know their fans don't like each other, and so they just troll them a little bit.
Martin has been in the NFL since signing with the San Diego Chargers as an undrafted free agent in 2009. He was released during final roster cuts that year, and then signed with the Carolina Panthers practice squad after clearing waivers. He was promoted to the Panthers active roster in November 2009 when Jordan Gross went on injured reserve. He appeared in seven games and had one reception for six yards. He spent 2010 with the Panthers, appearing in one game before landing on injured reserve. Nothing appears for him in 2011 until he signed with the Jaguars practice squad on December 2. He then signed a reserve/future contract with the Seahawks in 2012, and appeared in four games with one start. He caught four passes for 42 yards.
Martin was described by Rotoworld as a backup slot receiver. The 49ers had been considering Austin Collie, and likely will continue to do so. If Martin and the rest of the receivers don't step up in the slot, maybe the team considers Collie.
