What happened: Donald passed his physical before being officially reinstated to the active roster Monday. He can participate with Los Angeles moving forward.
Why it matters: The exemption provides temporary roster flexibility during opening-week preparations. His one-year deal is worth $20 million and can reach $30 million with incentives.
By the numbers: The exemption expires Friday, Sept. 11.
What to watch: Donald's practice workload and game status for the opener are the next checkpoints.
