Julian Edelman apologized Friday on Instagram for his recent positive test for performance enhancing substances.
"I am very sorry - I don't know what happened," Edelman said. "I've taken many, many tests obviously over the course of my career, and nothing like this has ever happened."
ESPN reported Thursday that Edelman is facing a 4-game suspenson for violating the NFL's performance enhancing substances policy. Edelman is appealing the suspension. It is not clear yet what substance he tested positive for.
"I apologize to the Kraft family, my coaches, teammates and fans," he added. "As this matter is being appealed, I can't say anymore but no matter what, I will be ready to play and pursue another championship with our team and for the Patriots fans around the world."
Edelman, 32, was in attendance at this week's minicamp and earlier voluntary workouts as he continues his recovery from a torn ACL suffered in Week 3 of the 2017 preseason that cost him the entire season.
This will be Edelman's 10th year in the league. In recent years, he's been one of Brady's favorite targets. In 2016, his last full season, he caught 98 passes for 1,106 yards and three touchdowns. Over his career, he has 425 career catches for 4,540 yards and 24 touchdowns.
The Patriots are scheduled to play Houston, Jacksonville, Detroit and Miami in the first four games of this season.
