The Chicago Bears have some protection in case safety Mike Brown falls victim to yet another injury.

The Bears and Brown on Tuesday agreed to restructure the final year of his five-year, $17 million contract.

Brown’s agent, Ethan Lock, confirmed that the two sides agreed to re-do the deal prior to April’s NFL draft. “It gives them some protection in case he gets injured again,” Lock told PA SportsTicker.

The Chicago Sun-Times reported that the base pay for final year of the deal has been reduced from Brown $2.44 million to $950,000. The newspaper reported that the difference can be made up through incentives that factor in playing time.

If Brown, 30, is injured before the season starts, his base salary will be trimmed to $320,000 the Sun-Times reported.

Brown, who signed the extension in 2003, has missed 43 regular-season games over the last four seasons due to various injuries. The eight-year veteran missed 15 games last season after tearing his ACL in a season-opening loss to San Diego on September 9.

The newspaper also reported that Brown is fully recovered from the devastating knee injury that ended his 2007 season, and was running with the first team at free safety during the first organized team activities on Monday.

Brown missed the Bears’ loss to Indianapolis in Super Bowl XLI due to a torn Lis franc ligament in his right foot, which limited him to six games that year. A second-round pick in 2000, Brown also tore his ACL in 2004.

The Bears’ heart-and-soul on defense, Brown has been productive when healthy. He has 449 tackles, four interceptions and seven forced fumbles to go with seven defensive touchdowns in 85 career games.
