Los Angeles Rams star Aaron Donald has drawn a line under his part in last Thursday's practice brawl against the Cincinnati Bengals, stating "what matters" is that he is ready for the season opener against the Buffalo Bills.

The defensive tackle was caught on camera in footage from a joint practice session between last season's Super Bowl finalists swinging a Bengals helmet as a weapon on August 25.

No ban has been handed down to him for his part in the fight, while Donald stated he did not wish to rehash the subject in an appearance on the AP Pro Football Podcast last week.

Speaking to media ahead of the NFL curtain-raiser against the Bills, the three-time Defensive Player of the Year reiterated his stance, while pointing out that nobody was injured in the incident.

"My main focus is Buffalo right now," Donald said. "I'm happy nobody got hurt in the practice and whatever, but my main focus is Thursday night against Buffalo.

"Everybody protected each other, everybody got out of the situation clean [and] healthy. So that's what matters. [I'm] ready for Week 1."

Defensive coordinator Raheem Morris meanwhile further added that the team treated the incident as a serious matter, but suggested it was an "error" of judgement more than an intentionally malicious move.

"You don't want to swing a helmet ever just at anybody in general, but there have been some helmets ripped off at times," he added.

"You never ever want to do those things. You don't want to have that on your resume.

"But at the same time, those things happen in practices. They're mistakes. They're errors and they're correctable when they happen at these times."
