What happened: Aaron Donald worked out for the Los Angeles Rams for a second time, listed as a workout participant on Sunday's NFL transaction wire, a day after the Rams beat the Kansas City Chiefs 20-12 in their preseason opener. Donald first worked out with the club on Aug. 5. Head coach Sean McVay said he won't put an 'invisible deadline' on Donald's decision.

Why it matters: A return would pair Donald with Myles Garrett atop the league's sack production, giving the Rams a pass rush McVay's staff has already called championship-caliber for a team entering the season as a preseason Super Bowl favorite. McVay said Saturday he's hopeful for clarity 'sooner rather than later' so the roster can plan around Donald's decision heading into Week 1.

What to watch: Rams open the regular season at the 49ers on Sept. 10, giving Donald's decision a working deadline even as McVay declines to name one.
