What happened: The rookie left Thursday's practice early, and New Orleans is gathering information before setting a return timeline. Kellen Moore said the issue arose from an awkward play.

Why it matters: The absence cuts into Tyson's preparation for his first NFL season. It also leaves New Orleans evaluating its receiver rotation without him during the preseason.

What to watch: The Saints' next update could establish the length of Tyson's absence and his availability for the regular-season opener.
