- According to Rapoport, Martin decided to call it a career rather than undergo back surgery.
- Rapoport adds that Martin’s back injury would have cost him the entire 2015 season.
Martin, 25, had another year remaining on his four-year, $4,784,267 rookie contract, which includes a $1,042,400 base salary for the 2015 season.
Martin is a former second-round pick of the Dolphins back in 2012. He lasted two years in Miami before he left the team due to the bullying situation that resulted in Richie Incognito taking an extended leave from the team.
The Panthers claimed him off of waivers from the 49ers back in March.
In 2014, Martin appeared in 15 games and played a total of 661 snaps for the 49ers. Pro Football Focus has him rated as the No. 60 offensive tackle in the league out of 84 qualifying players.
