James Harrison has been busy this offseason.

The Pittsburgh Steelers linebacker has been in the gym crushing workouts like he usually does—but he’s also had to spend some time taking drug tests for the NFL.

Harrison posted a photo on Instagram of his test, writing: “Let’s see…today marks my 3rd random ped test this offseason in about as many months #March29th #April27th #June6th #nopedsneeded.”

Under the collective bargaining agreement between the NFL Players Association and the NFL, the league can test players up to six times during the offseason. Players are selected at random by an independent testing administrator, and the NFL does not have access to the testing system, according to ESPN.

Harrison previously spoke about getting tested by the league, telling Pennlive.com during the 2016 season: “I’m starting to think it’s not as random…I just wish I had that much luck with the lottery. That’s all.”

Harrison added another photo to his Instagram following the original post about the test:

Harrison didn’t let the test bother him too much, though.

Soon after finishing up, he was back in the gym—again:
