When it comes to next week's Fed meeting, traders will be looking to make a play on Janet Yellen's words.

Fed-watchers are eager to see whether the language of the Federal Reserve's post-meeting statement changes to a more hawkish tone.

According to the "Fast Money" traders, the alteration of a few choice words regarding the Fed's plans to keep rates low for a "considerable time" could have a significant impact on stocks.

On Thursday, Tim Seymour of Triogem Asset Management said he thinks the Fed will strike a more hawkish tone.

"I think there will be enough of a hawkish directive that is different than what we've heard," he said. According to Seymour, that tonal shift "is enough in the short-run to unsettle markets."

OptionMonster's Pete Najarian took a similar stance.

"I actually think there will be some change in the language," he said, adding that any shift would be followed by "backpeddling" to assuage fears.

Najarian recommended buying protection leading up to the event, but said that ultimately a change in Fed policy would be a positive, calling any pullback "an incredible buying opportunity."

The FOMC is scheduled to conclude its two-day meeting on Wednesday.
