The fight occurred before practice Thursday, and Pryor was not on the field during the portion of practice open to the media, according to the Akron Beacon Journal.
NFL Network's Ian Rapoport initially reported the release was expected after Pryor got into a fight with a teammate before practice on Thursday. Browns coach Hue Jackson said there are no plans to release Lewis. Jackson called what happened an internal matter.
The hirsute Pryor was a first-round pick by the New York Jets back in 2014 but has now worn out his welcome with two different franchises.
With the Browns coming off a 1-15 season and needing playmakers on both sides of the ball, Pryor appeared to be in an ideal spot that would help him turn his career around.
Pryor is still playing under his rookie contract - 4 years, $8.5 million. The 5-foot-11, 207-pound safety recorded 191 tackles, 11 tackles for a loss, 14 passes defended, two interceptions, and two forced fumbles in his first three seasons with Gang Green.
