The Texans have released former first-round cornerback Kevin Johnson, according to Ian Rapoport of NFL.com (on Twitter). This was the expected move after the Texans shopped Johnson but were unable to find a suitable deal. 
Johnson, a talented corner, was due $9.069MM on his fifth-year option. The option was guaranteed for injury until the start of the league year next week, so it appears that Johnson has received a clean bill of health. He’ll now have an opportunity to shop his services before the start of free agency on March 13.
Johnson’s 2018 season was mostly lost due to concussions. In September, the Texans parked him on IR and he was unable to return.
Before the move, the Texans still had plenty of cap space with $80.9MM available. Their total, good for third-most in the league, inches up a bit after cutting Johnson. Some of that money will probably go towards fortifying a cornerback group that has clear issues: Johnathan Joseph will turn 35 this year,Aaron Colvin missed extensive time last season, and Shareece Wright is set for free agency next week.
