Source: Roddy White has sprain
If this were the regular season, White would play, the source said. But the Falcons do not want to push him before he's ready in the preseason.
White, 31, suffered the injury in the Falcons' 27-23 loss to Baltimore on Thursday night.
The nine-year veteran has had six consecutive 1,000-yard receiving seasons and is a key piece in Atlanta's passing game, one of the NFL's most potent.
