The Lions got to work on their 2014 salary cap in a big way on Thursday.
The team released veteran receiver
Delmas, 26, was due $5.5 million in base salary and a $500,000 roster bonus.
A 2009 second-round pick by the Lions has battled through knee issues the last three years. He missed five games in 2011, six in 2012, and, despite playing in all 16 games in 2013, missed a huge chunk of practices.
Delmas' play on the field seemed to be affected by the lack of practice time and his knee problems.
Delmas recorded 331 tackles, five sacks, six interceptions and four forced fumbles in five years with the Lions.
The team will no-doubt be in the market for a safety via the draft or free agency this offseason.
