What happened: Aaron Donald worked through drills with Los Angeles after ending his retirement and signing a one-year contract. The session moves his comeback into on-field preparation.
Why it matters: His return adds an experienced option to the Rams' defensive front. Los Angeles opens the season in the NFL's first regular-season game in Australia.
By the numbers: Donald's deal is worth $20 million and can reach $30 million with incentives.
What to watch: Watch Donald's workload before the Rams leave for Australia and set their opening-week rotation.
