The Buffalo Bills are adding depth at safety after injuries hit the position at training camp.

Veteran Kareem Jackson signed a one-year deal with the Bills on Tuesday.

Jackson, a 2010 first-round pick by the Houston Texans, is entering his 15th NFL season. He has started 193 of his 203 regular-season games with the Texans and Denver Broncos. Jackson has 954 career tackles, 22 interceptions, 7, forced fumbles, 7 fumble recoveries, 3 sacks and 110 passes defensed.

Jackson was released on Christmas Day last year by the Denver Broncos following his second suspension of the season. Houston signed him up for the final two games and the playoffs.

Buffalo safety Mike Edwards is week-to-week with a hamstring injury, head coach Sean McDermott said Monday. Rookie Cole Bishop left practice with an apparent arm injury Tuesday.

That left Taylor Rapp starting at strong safety, with Damar Hamlin, Kendall Williamson and Dee Delaney as the only remaining safeties on the roster.

Here are three things to know about Jackson:

Kareem Jackson was suspended twice and fined four times in 2023

Jackson was suspended twice totaling six games in 2023.

Jackson garnered his first suspension following an ejection for a hit to the head of Green Bay Packers tight end Luke Musgrave in Week 7. That followed an illegal hit on Las Vegas Raiders wide receiver Jakobi Meyers in Week 1, a helmet-to-helmet hit that earned an ejection and gave Washington Commanders tight end Logan Thomas a concussion in Week 2, and an unnecessary roughness fine against the Miami Dolphins in Week 3. Jackson appealed and the suspension was reduced from four games to three games.

Jackson's return lasted one game. The league decided Jackson made an illegal hit on Minnesota Vikings quarterback Joshua Dobbs for lowering the crown of his helmet in his first game back and issued him a four-game suspension the next day.

Jackson was fined a total of $86,670 for four illegal hits last season and lost $838,889 in missed game checks.

Jackson said he shouldn't be labeled as a dirty player and feels he's the poster child for the league to prove a point.

"I was told that I'm responsible for the offensive guys' protection," Jackson said last year. "So, I'm not really sure how I protect myself, make plays and protect him (the offensive player) as well. But that's what I was told, and I'm not really sure what I do moving forward as far as playing this game, so, hopefully I'll figure it out."

Kareem Jackson is the oldest player on the Bills roster

Jackson, 36, is older than the safeties the Bills parted with in the offseason. Micah Hyde and Jordan Poyer, who were paired in Buffalo's secondary for seven years, are each 33 years old.

Buffalo has seven players older than 30: OL La'el Collins (31), DT DeShawn Williams (31), DT DaQuan Jones (32), S Sam Martin (34), LB Von Miller (35) and Jackson.

He started the Kareem Jackson Foundation to honor his mom and sister

The Kareem Jackson Foundation supports women and children with cancer. He also hosts an annual Christmas shopping spree for kids.

Jackson's mother, Rossalyn Jackson, is a two-time breast cancer survivor. His sister, Shari, overcame leukemia as a child.

Shari was diagnosed with leukemia when when she was 6 years old in 1992. Kareem was 4 and spent a lot of time at the hospital in Georgia, traveling to and from visiting his sister and his school.

Her chemotherapy treatment lasted three years and was finishing when Rossalyn was was diagnosed with cancer for the first time in 1995. Sometimes their treatment overlapped and mom couldn't visit her daughter because she was immunocompromised.

Rossalyn's breast cancer came back in 2002 but she was cancer free later that year. Shari is also cancer free.
