The Oakland Raiders released linebacker Derrick Johnson after he made just six appearances with the team.
"We certainly wish Derrick Johnson the best," Gruden said.
Although the 35-year-old University of Texas product was a longtime stalwart for the Chiefs, earning four Pro Bowl selections and a First Team All-Pro nod, he made a limited impact for the Raiders.
He collected 17 combined tackles with no sacks, forced fumbles or interceptions in mostly a reserve role as the Raiders struggled to a 1-5 start.
"I put pressure on myself to play at a high level, regardless of my role," Johnson told reporters last month. "It's not 100 percent of the snaps anymore, but it's a good amount where I have to know my stuff because my name is going to be called a lot."
While the Raiders sheltered his playing time, it's worth noting Pro Football Focus graded him as the league's 35th-best linebacker through six weeks.
So Johnson may receive free-agent interest from a contender to fill a similar void elsewhere. It's unclear whether he could handle an every-down role, though.
Meanwhile, the Raiders called up fellow linebacker Jason Cabinda from the practice squad in the corresponding move. He should assume the Johnson's snaps following the team's Week 7 bye.
