Aaron Donald is expected to miss the Los Angeles Rams' Week 1 opener against the Indianapolis Colts.

Donald is holding out as he seeks a long-term contract.

Donald has not shown up throughout the Rams' training camp and preseason, racking up approximately $1.4 million in fines. Donald has a base salary of $1.8 million.

Both sides have made little progress on a contract extension for Donald that could eventually make him the game's highest paid defensive player.
