Detroit Lions star Jameson Williams has a cousin in the NFL.

The league has had plenty of family members join its ranks over the years, but it is pretty rare for them to play at the same time while also being top-tier.

This happens to be the case with Jameson and Kyren Williams, who are actually closely related. The latter, who plays as a running back for the Los Angeles Rams, is first cousin to the former.

Lions TV Network’s Dannie Rodgers revealed as much this Thursday, which came as quite a surprise as it is not listed on either player’s Wikipedia page –  at least, it wasn’t before Thursday.

“#Lions Jameson Williams and #Rams Kyren Williams are cousins. Actual first cousins lol,” Rogers tweeted.

“No way!? That’s pretty cool,” a fan said in the comments.

“Some scary athletic genes in that family,” another pointed out.

“That’s actually really interesting and pretty cool,” said a third.

Rogers revealed Jameson told her so himself.

Jameson Williams & Kyren Williams Didn’t Have Similar Paths Into The NFL

Apart from having the same last name, the players are both from St. Louis, Missouri.

Jameson initially committed to Ohio State but transferred to Alabama in 2021 after hardly being played by the Buckeyes.

He led the SEC in receiving yards, yards per catch, and touchdowns as a junior, recording 79 receptions for 1,572 yards and 15 TDs. He was drafted as the No. 12 overall pick by the Lions in 2022.

Kyren, meanwhile, went to Notre Dame and became a starter in his second season. He recorded two consecutive seasons with over 1,000 rushing yards and was a Second-Team All-American in 2021. He was the 164th overall pick in 2022, earning Pro Bowl and Second-Team All-Pro selections last season.
