Oklahoma receiver Marquise Brown is headed to the NFL.

After two seasons with the Sooners, Brown announced he will skip his senior season and begin his professional career:

Here's what he said in the tweet above:

"This journey has been anything but easy, but through the trials and tribulations Sooner Nation has accepted me over the past two years and has become one of the most supportive fan bases I have ever been apart of, and for that I say thank you." Brown wrote in part. "To coach Stoops, I want to say thank you for always believing in me and taking a chance on an undersized kid to play on a big stage. To coach Riley, coach Simmons and the rest of the staff, I want to say thank you for always pushing me to better myself each and every day. I love you guys for that.

"As for my teammates, I couldn't ask for a better group. I love all of you and wouldn't trade you guys for anybody in the world. To all of my Pop Warner, high school and JUCO coaches, I want to say thank you for being a part of my journey, but it isn't over yet."

Brown has 2,413 career receiving yards, good enough for sixth all-time in Oklahoma history.

Oklahoma will miss Brown's speed in 2019, but the Sooners have quality replacements rising up the ranks. Oklahoma has signed one of the best receiver recruiting classes in recent memory, headlined by Allen High School product Theo Wease.

Redshirt freshman Charleston Rambo is the early favorite to replace Brown in the starting lineup. When the Hollywood, Fla., native was unable to go in the Orange Bowl, Rambo stepped in and caught three passes for 74 yards and a touchdown.

Junior offensive lineman Cody Ford and junior running back Rodney Anderson have already declared for the draft.
