Baltimore signed James (undisclosed) to its practice squad Wednesday, Ryan Mink of the Ravens' official site reports.
Jovaughn Gwyn fractured his fibula during Baltimore's contest against the Cowboys in Week 3 in Brazil, and veteran Ethan Pocic suffered a serious knee injury in that same game, prompting the Ravens to add some organizational depth at center. James primarily served as a backup at the position for the Chargers in 2025.
