Bears sign Brittain Brown and waive Ameer Speed with an injury designation, expanding a backfield that is already crowded. Brown’s UCLA burst behind the Raiders in 2022 (615 yards, seven rushing TDs) offered a glimpse of a decisive, power-pace back with special-teams value. After an injury-marred 2023 and a Seahawks practice-squad stint in 2024, he’s back in the NFL in Chicago, where he’ll compete for touches behind Khalil Herbert and the rest of a multi-back group. Speed’s exit creates another injury-designated roster move for a team still hashing out the roles at corner and safety. Brown’s addition tightens depth, and the weekend workouts featuring Jamaal Williams hint at a larger exploration of a bruiser complement. The Bears are quietly building a flexible RB room that could swing fantasy upside if Brown seizes a defined role in a committee.
