(CNN) -- It's a simple thing, really, the rubber and stainless steel band that a well-known CEO frequently wears around his wrist.
But the Nike FuelBand that Apple's Tim Cook has been seen sporting at multiple public events is just one clue about a possible deal between Apple and Nike that could be part of the sales pitch when a rumored Apple watch hits the market.
Late on Friday (the traditional time of the week for companies to release bad news), came a news report that Nike had laid off much of the team responsible for the FuelBand and would not continue to update the line of wearable gadgets, which measure physical activity and monitor things like heart rate and calories burned.
Nike had planned to release a new, thinner FuelBand in the fall, but those plans have reportedly been shelved and the company won't say whether there will be a new one. Nike has said it plans to continue supporting the current FuelBand for the "forseeable future" and that new color options will be available.
Still, the retreat seems odd for a company that has made its name in sports equipment -- and has led to speculations that Nike may be working on a new partnership with Apple.
"Obviously Apple has enjoyed a healthy relationship with them over the years," said Brian White, a Cantor Fitzgerald & Co. analyst who follows Apple. "Our view has been that the fitness band will largely fold into the smartwatch in the future and most of the players will exit the market. If I were them, makes more sense to partner with Apple, but that is just my opinion."
Nike spokesman KeJuan Williams said in an email that FuelBand remains "an important part" of Nike's business. He confirmed there will be a "small number" of layoffs and emphasized the company's continuing work on digital products, including partnerships with companies like Apple.
"Partnering with industry-leading tech companies is nothing new for Nike," Williams said. "We have been working with Apple to develop products since 2006, when the two companies introduced Nike+ Running, and Nike has since create Apps for the iOS including Nike+ Training Club, Nike+ FuelBand and Nike+ Move which launched in Fall 2013.
"Building on these successful products and services, Nike and Apple are partnering on emerging technologies to create better solutions for athletes."
Could that partnership evolve into a forthcoming Apple-Nike wearable product? That is still just conjecture at this point. But consider:
-- Already, Apple's iOS system is the only mobile system that can be used with the Fuel Band and its set of apps.
-- Apple is the highest-profile company that has not yet entered the wearable tech field -- despite the fact that rumors of an "iWatch" have been swirling for years. With Google, Samsung and other competitors already selling wearable gear, it would make sense for Apple to get into the game sooner rather than later.
Apple's Worldwide Developers Conference is set to begin on June 2, and the company has used the event in the past to announce new products.
Alternately, Apple has made a habit of introducing a new iPhone every fall, in advance of the holiday shopping season. It would certainly make sense to unveil a new product then as well.
Apple did not reply to a message seeking comment for this story.
