NFL fans think they’ve spotted a cryptic clue that Christian McCaffrey’s wife Olivia Culpo could be pregnant.

The San Francisco 49ers star running back has been sidelined with Achilles tendinitis in both legs since the beginning of the season.

Stunning model Culpo’s Instagram post was captioned: “A little bit of everything lately‍️‍.”

But buried deep within the 17-slide photo dump was a classic picture commonly used in pregnancy announcements.

McCaffrey, 28, had his hand placed over his wife’s abdomen, with the pair smiling into each other’s eyes.

And the black and white photo had fans asking the same question – are the newlyweds expecting their first child?

The loved-up couple got married in June surrounded by famous friends and familiar NFL faces such as 49ers quarterback Brock Purdy.

One fan wrote: “I see a pregnancy announcement in the future.”

A second said: “Why did my heart stop with the hand placement on the belly? You look SO happy in all of these.”

A third replied: “Best not to speculate. But it seems that way.”

Another added: “Why am I feeling like this is a massive baby hint. If it is, I’m so happy for them.”

One more wrote: “Can’t wait for the announcement .”

While many comments referenced McCaffrey’s fitness, with one writing: “Please tell your husband to get healthy. We are dying out here .”

The 49ers have won three and lost three of their opening six games this season, but sit top of the NFC West.

Kyle Shanahan’s side most recently triumphed to a 36-24 win against the Seattle Seahawks, but face the Kansas City Chiefs next on Sunday.

McCaffrey is unlikely to face the Chiefs in the much-anticipated Super Bowl rematch.

Replacement running back Jordan Mason, who has masterfully filled McCaffrey’s large shoes, exited Thursday night’s game with a shoulder injury.

McCaffrey was fresh off an Offensive Player of the Year award in 2023 before his injury, which added to his list of accomplishments.

His other feats include three Pro Bowl selections, three All-Pro first-team selections and a Super Bowl appearance – which ended in heartbreaking defeat in overtime in February.

The Chiefs flashed their latest piece of jewelry at a special ceremony on Thursday, June 13.

The new bling features the years of Kansas City’s Super Bowl wins – 1969, 2019, 2022 and 2023.

It also has a handwritten drawing of Andy Reid’s ‘Tom and Jerry’ play which won Super Bowl LVIII at Allegiant Stadium in Las Vegas, Nevada.

Kansas City beat the San Francisco 49ers 25-22 in overtime in February.

And the rings feature 22 diamonds to represent the points Kansas City scored in the second half and overtime.

Nineteen diamonds also represent their 11 straight winning seasons and eight AFC West titles in a row.

While there is also commemorative patch for the late Norma Hunt, the matriarch of the family which owns the Chiefs who died last summer.
