Many fans took to Twitter to share their thoughts, admitting they didn’t even know tripping was illegal in the NFL.

Some knew about the call but declared it ‘egregious’, while others were surprised the refs bothered to call a seemingly minor foul.

Why is tripping illegal in the NFL?

After the foul was called, many questioned why tripping is illegal in the NFL.

If the aim is to take the QB down, tripping seems a logical and legitimate way of doing so.

However, as defined by the 2019 NFL Rulebook (Rule 3, Section 40): “Tripping is the use of the leg or foot to obstruct any opponent (including a runner).”

Rule 12, Section 1, Article 8 makes tripping a prohibited act.

The reason is likely due to the prevention of injuries, in the same way clothes-line and shoulder tackles under the face mask are illegal.

It could also result in a serious injury to the person committing the foul, who could have his leg stamped on or broken.

Other have hypothesised it could be down to rewarding the skill of blocking, rather than tripping.

Whatever the case, it seems an unpopular rule many fans weren’t even aware of.
