What happened: Baltimore Ravens wide receiver Zay Flowers did not participate in Wednesday's practice due to a hamstring injury. Offensive tackle Ronnie Stanley, outside linebacker Trey Hendrickson, and defensive end Calais Campbell were also held out.

Why it matters: Flowers sustained the hamstring issue during the season opener. His availability is critical as Baltimore prepares for a Sunday matchup against the Dallas Cowboys in Rio de Janeiro.

What to watch: The Ravens will release further injury reports on Thursday and Friday ahead of the international game.
