What happened: Coach Jesse Minter said starting center Jovaughn Gwyn injured his ankle and backup Ethan Pocic injured his knee, with both described as potentially long term. Minter said rookie first-round pick Vega Ioane will prepare to play center while the team considers adding another center.

Why it matters: Losing the top two centers empties the most specialized depth spot on the offensive line in one day. Shifting a rookie first-round pick to center plus a possible outside addition points to an immediate reshuffle up front.

What to watch: Watch whether Baltimore adds a center and how Ioane splits practice reps in the week ahead.
