What happened: Aaron Donald will not travel to Australia and will be inactive Thursday against San Francisco. He did not practice with Los Angeles during training camp or the preseason.
Why it matters: The Rams must open against a division rival without the centerpiece of their defensive overhaul. His roster exemption gives Los Angeles flexibility while he ramps up.
By the numbers: Donald is a three-time Defensive Player of the Year and has a two-game roster exemption.
What to watch: Week 2 against the New York Giants is his earliest possible return.
