What happened: Bowers sustained the injury in training camp and received the diagnosis last week, according to [Yahoo Sports](https://sports.yahoo.com/nfl/breaking-news/article/raiders-all-pro-brock-bowers-reportedly-had-meniscus-trim-that-will-sideline-him-for-season-opener-maybe-longer-200007786.html).

Why it matters: Las Vegas will open the season without its All-Pro tight end, with Bowers' absence for the opener already established.

What to watch: Watch the Raiders' practice participation updates and game-status designations for his return.
