Los Angeles Rams defensive tackle Aaron Donald was widely considered the league's premier pass rusher going into the 2018 NFL season. Unfortunately, he still has yet to record his first sack this season after three games.

Some may be concerned with his inability to bring down the quarterback thus far. However, Donald knows it is only a matter of time, according to Gary Klein of the Los Angeles Times.

Donald has established himself as one of the most dominant defensive players in the league. He finally got paid as such after signing a lucrative six-year, $135 million deal. There is concern that he has not given the Rams any bang for their buck after failing to register a sack. However, it is still far too early to press the panic button.

Donald is still generating plenty of pressure on opposing quarterbacks. He has already registered 15 pressures through the first three games. Furthermore, he is a notoriously late starter when it comes to recording sacks. He had just one in the first three games of last season, however, he still managed to finish the year with a career-high 11 sacks.

It should also be noted that Donald is not the only one struggling to bring down the quarterback. The Rams' defense as a whole ranks second-to-last in sacks with just four. Defensive coordinator Wade Phillips will have to figure out a way to create even more pressure up front.

Meanwhile, Donald will look to get the ball rolling on Thursday versus the Minnesota Vikings.
