Coach Sean McVay told reporters after the session that Donald, the club's unquestioned defensive centerpiece, looked "fast and fresh" in practice, per the team's official website.
McVay said he anticipates Donald suiting up against Washington, adding that if the behemoth plays, he will start the game -- with or without a new deal.
"The way I chose to handle it is the way I chose to handle it," Donald said of his decision to hold out. "And I'm here now."
We fully expect Donald to play, giving defensive coordinator Wade Phillips a titanic Christmas gift three months early.
As Washington's former offensive play-caller, McVay knows his former team -- and their quarterback, Kirk Cousins -- as well as anyone in the NFL.
That knowledge is doubly dangerous with Donald back in the mix as one of the league's premier, game-plan-wrecking whirlwinds.
