Martin signed a one-year contract with the Bears on Tuesday, Brad Biggs of the Chicago Tribune reports.

EDGE Analysis

Martin, who was cut by the Bears in training camp, re-signed with the team after Antrel Rolle suffered a foot injury in Sunday's win over the Raiders, putting his status in question for the Week 5 game against the Chiefs. If Rolle is unavailable for that contest, Martin or backup Harold Jones-Quartey could see the start at strong safety.

Martin was released by the Bears during final roster cuts, the Chicago Tribune reports.

EDGE Analysis

The Bears determined that Harold Jones-Quartey, who was claimed off waivers from the Cardinals, would be a better option for their safety ranks than Martin. He had appeared in 13 games last season for the Bears, recording 16 tackles and an interception.

The Rams are hosting free agent S Sherrod Martin on Monday. Martin visited the Chiefs in early April, but hadn't been heard from since. The 28-year-old was selected by the Panthers 59th overall in the 2009 draft.

Free agent S Sherrod Martin is visiting the Chiefs on Thursday. Martin, 28, started 31-of-32 games for the Panthers from 2010-11, but he was demoted to backup duties behind Haruki Nakamura and Charles Godfrey last season. The former second-round pick shredded both his ACL and MCL in December, so the Chiefs are likely just checking in on him.

The Charlotte Observer expects the Panthers to let free agent S Sherrod Martin (ACL surgery) walk. The former second-round pick is barely two months removed from wrecking his knee. Martin started 31 games between 2010-11, but came off the bench last season. He could have a hard time landing a contract before Week 1.

Panthers S Sherrod Martin left the stadium on crutches after sustaining a right knee injury in Sunday's loss at Kansas City. "They're concerned about the knee, obviously," coach Ron Rivera said. "He'll get X-rays and MRIs and then we'll know more as far as that's concerned." Martin's snaps had increased of late while Haruki Nakamura's have been scaled back.

Sherrod Martin is running as the Panthers' starting free safety in OTAs. Martin is "on alert" after the Panthers signed Haruki Nakamura and Reggie Smith, but still has the inside track to a starting job. It's possible Martin and Nakamura could end up splitting snaps, with Martin playing obvious passing downs and Nakamura obvious running downs.

The Charlotte Observer confirms newly signed Haruki Nakamura will compete with FS Sherrod Martin for the starting job. Martin struggled badly at times last season, missing tackles and giving up too many big plays. Although Martin may have the edge in coverage skills, Nakamura is better in run support.

Panthers FS Sherrod Martin has been ruled out for the remainder of Sunday's game with a "sickness". Details are unknown, but Martin had five tackles (four solo) in the first half. The Panthers' No. 3 safety is usual nickel back Jordan Pugh.
