Jackson was released by the Bills on Tuesday, Jeremy Fowler of ESPN.com reports. Jackson joined Buffalo in July in an attempt to complete a 15th NFL season, but the 36-year-old ultimately was unable to earn a spot on the team's final 53-man roster. The Alabama product could still draw interest from other teams looking to improve their depth with an accomplished veteran safety.
Jackson signed a one-year contract Tuesday, Chris Jenkins of the Bills' official site reports. Potential starter Mike Edwards has a hamstring injury that's more than a day-to-day thing, so the Bills are bringing in reinforcements. At 36 years old, Jackson is on the downside of his career, but he has a strong history as a key starter for both the Texans and Broncos for a number of years and can help the Bills if they run into depth issues.
