What happened: Baltimore Ravens wide receiver Zay Flowers was held out of Wednesday's session. He is managing a hamstring injury sustained in the season opener that prevented him from playing in Week 2.

Why it matters: The Ravens are preparing to face the Dallas Cowboys in an international game in Rio. Flowers' inability to practice early in the week casts doubt on his availability for the contest.

What to watch: His participation levels on Thursday and Friday will finalize his injury designation for the weekend.
