On August 11, 2013, Martin signed with the Chicago Bears but was released on August 25. He was brought back by the Bears on November 13 after Charles Tillman was placed on injured reserve. Martin appeared in seven games in 2013 for the Bears, recording a tackle on defense and six on special teams. Martin was a free agent after 2013, but on February 24, 2014, he signed a one-year deal with Chicago. He was waived on May 28, 2014.
On January 20, 2013, Martin's home was invaded while he was out with his team at the AFC Championship game where the Baltimore Ravens defeated the Patriots 28-13; two masked men back forced their way into Martin's home in Aurora and held his wife Alexa Martin, and their three children at gunpoint. The police did not get a good enough description of the suspects to pursue a case. Police spokeswoman Cassidee Carlson said the suspects took some valuables, but wouldn't go into further detail about what was taken.
