Giants defensive captain Jonathan Casillas had a feeling this Instagram post was a mistake.

While enjoying a tropical getaway in the Dominican Republic, Casillas uploaded a few shots from his vacation to Instagram, including a shot of him sitting aboard an ATV and puffing on a hand-rolled cigar. The 29-year-old linebacker predicted trouble ahead with a series of ominous hashtags.

“Hand rolled Dominican cigar and ATV’s… great combination!! #iknowitlookslikeablunt #andIprobablyshouldnthavepostedthis #butthepicsolit #shoutouttotheshooter,” Casillas wrote.

Like clockwork, the NFL flagged Casillas to submit to a drug test a day later.

“Random lol, what a coincidence,” he shared alongside a screenshot of a text notification from the league.

Casillas, who geo-tagged his latest share from Punta Cana on Monday, is set to report for the Giants offseason OTAs starting April 18.
