Mayfield said he's going to take a break from "all social media for the foreseeable future."
Ironically, the polarizing QB went on his Instagram page Wednesday to announce his hiatus from tweeting and posting.
"Gotta do what's best to focus on me, my family and loved ones," Mayfield wrote. "Appreciate all the support. Time to get right."
Mayfield concluded his message by also including a contact for anyone making business or marketing inquiries.
Mayfield recently concluded a dreadful, injury-filled fourth season with the Browns, who were among the NFL's most disappointing teams. Cleveland went 8-9, missed the playoffs and dealt with drama, much of it involving Mayfield.
Late in the season, Mayfield went on Twitter to dispel a story about issues between him and coach Kevin Stefanski. He called the report "clickbait" and added that "many other Cleveland local media continue to be drama stirring reporters with no sources or facts."
Mayfield's wife, Emily, also used her Twitter platform to claim he received death threats. Mayfield downplayed those and described his attackers and critics on social media as "keyboard warriors."
The 26-year-old Mayfield injured his left, non-throwing shoulder in Week 2 while trying to make a tackle and struggled all season. He recently underwent surgery in Los Angeles for a torn labrum and is expected to need more than four months to recover.
The team said he should begin light throwing in April.
Following the season, both Stefanski and Browns general manager Andrew Berry publicly supported Mayfield by saying they believe he will bounce back next season as their starter. However, it's likely the team will at least explore other options at quarterback during this offseason.
Mayfield is under contract next season for $18.9 million after the team exercised his fifth-year option.
