What happened: Los Angeles Rams defensive tackle Aaron Donald, cornerback Jaylen Watson and tight end Colby Parkinson returned to practice Thursday as limited participants. Safety Quentin Lake did not participate in the session due to a hip injury sustained during Sunday's 24-20 victory over the Philadelphia Eagles.

Why it matters: The defensive reinforcements arrive as Los Angeles prepares to face a Buffalo Bills offense led by quarterback Josh Allen. Watson's return is notable after he dislocated his right shoulder against the Denver Broncos in Week 3, an injury initially expected to sideline him for several weeks.

What to watch: Head coach Sean McVay indicated the team plans to ramp up the returning players' workloads throughout the week before hosting the Bills at SoFi Stadium.
