The Bears keep adding to their secondary.
Chicago has agreed to terms with defensive back Cam Lewis on a two-year deal, according to ESPN's Jeremy Fowler. Lewis, 28, spent his entire six-year NFL career with the Buffalo Bills as an undrafted free agent out of the University at Buffalo, carving out a durable role as the primary backup nickel corner and a core special teams contributor. The deal becomes official when the new league year opens Wednesday, March 11.
Who Lewis Is
The short version: he is exactly what the Bears need him to be — a dependable, versatile defensive back who can line up in the slot, outside, or at safety without missing a beat. Lewis spent six seasons in Buffalo as the primary backup to nickel cornerback Taron Johnson, developing the kind of scheme versatility and special teams value that makes players like him genuinely hard to replace. Johnson also left Buffalo in free agency this week. So did Lewis. The Bills lose both pieces of their nickel position in the span of a few days.
Over his 76 regular-season games in Buffalo — he made 14 starts — Lewis totaled 166 tackles (120 solo), five tackles for loss, 11 passes defensed, one interception, and three forced fumbles. He also appeared in 11 playoff games, including one start. In 2025, he played all 17 regular-season games, started four, and posted 43 tackles, four passes defensed, and two forced fumbles while handling 38 percent of Buffalo's defensive snaps and 50 percent of their special teams snaps. He wasn't a featured player in Buffalo's defense, but he was a reliable one — particularly as an emergency starter who held up when asked to do more than his depth role required.
The financial terms have not been disclosed.
The Nahshon Wright Replacement
As noted in last week's free agency report card, the Bears lost one of the more unlikely success stories of the 2025 season when Nahshon Wright departed for the New York Jets on a $5.5 million deal. Wright arrived in Chicago as a practice squad castoff from Minnesota, developed under Dennis Allen's system, earned a Pro Bowl nod, and cashed in. That's a good story and a real roster hole. Lewis isn't a one-for-one replacement — Wright was a cornerback who moved around the secondary, Lewis is a nickel/safety hybrid — but the thread connecting them is the same: versatile defensive backs who understand how to function in a scheme-heavy secondary without requiring starter-level investment.
Allen's defense asks a lot of its secondary players. The pre-snap disguise, the multiple alignments, the willingness to blitz from unexpected spots — none of that works without depth that can execute the same looks the starters do. Lewis played in a similar system in Buffalo under Sean McDermott, one of the more sophisticated defensive minds in the league, and that translates. He's not going to be confused by complexity. That's worth something.
Where He Fits
The Bears' secondary entering 2026 is anchored by Coby Bryant, who signed a three-year, $40 million deal Monday as the starter at one safety spot. The second safety slot remains unsettled — Kevin Byard and Jaquan Brisker are both still unsigned — and the cornerback depth chart is being rebuilt from scratch with Jaylon Johnson locked in as the one true certainty. In that context, Lewis is a connector piece: someone who can slide into any of those roles in a pinch and not create a liability.
At 5-foot-9 and 183 pounds, Lewis is undersized for safety work but well-sized for the nickel. He'll likely see his snaps concentrated there, backing up whoever the Bears settle on as the starter in the slot — and potentially starting early in the season if that question isn't answered cleanly before the opener. His special teams value alone probably justifies the contract. The two forced fumbles he generated in 2025 on just 50 percent of Buffalo's special teams snaps are a nice reminder that he's not just a defensive depth body.
This is the kind of move that doesn't generate much immediate excitement but tends to look smart by October. The Bears' secondary depth was a legitimate concern after Wright left, Jaylon Jones was not retained, and Gervarrius Owens is also heading for the open market. Lewis isn't a solution — the secondary still needs Byard or Brisker back, ideally both — but he's the kind of player who keeps a room from being thin when it can't afford to be.
