Donald was rendered inactive for the game, ostensibly due to his absence during the preseason as he held out for a new deal. He is expected to play Week 2 against the Washington Redskins.
"The way I chose to handle to handle it is the way I chose to handle it. And I'm here now," Donald said Wednesday, according to NFL Network's Andrew Siciliano.
Donald is the Rams' best defensive player by a significant margin, but his club didn't miss him too much Sunday in a 46-9 rout of the Colts.
The 26-year-old is widely considered the NFL's best defensive tackle after earning three consecutive Pro Bowl selections and two consecutive appointments to the All-Pro first team.
Donald will earn $1.8 million in base salary during the 2017 season and holds a $3.2-million cap hit.
