Cowboys fans, get ready to update your shopping lists. Rookie safety Caleb Downs isn't just making waves on the field—he's already got the hottest jersey in the NFL, topping all rookie sales. But if you were planning on grabbing that No. 18 jersey, you might want to hold off.

Downs has made a quick switch from No. 18 to No. 13, as reported by the Cowboys' official website. During rookie minicamp, he sported the No. 18, but he'll be wearing his new digits for OTAs. It's a fast change that has fans buzzing, especially considering his jersey is already a top seller among rookies.

However, here's the kicker: the number situation might not be settled just yet. Tommy Yarrish of the Cowboys' official site warns that the current number is "subject to change and still could be different between now and the beginning of the regular season." That means your No. 13 jersey could be a collector's item—or obsolete—before the first snap.

Downs wore No. 2 at Ohio State, and that number is currently held by cornerback Cobie Durant, who signed a one-year deal with the team in March. There's a chance Downs could work out a deal with Durant, or the Cowboys might step in to reclaim the number for their star rookie. If that happens, expect another jersey shuffle.

For fans looking to buy, timing is everything. If Downs eventually lands No. 2—and Durant doesn't return in 2027—any jerseys purchased in 2026 could become relics of a brief era. So, whether you're a die-hard collector or just want to rep your favorite rookie, keep an eye on the number board. This story is far from over.
