What happened: Larkin will miss the start of Detroit Red Wings training camp because of an injury. The absence removes a key piece from the club's opening on-ice work as camp gets underway.

Why it matters: Camp already carried roster uncertainty after Larkin said he would attend Red Wings camp after requesting a trade. Missing the first days of camp delays an early read on how Detroit plans to handle that situation and its leadership reset.

What to watch: Watch for Detroit to clarify when Larkin returns to the ice and whether his absence extends into preseason preparations.
