The Lions also retained another member of their secondary, re-signing safety Tavon Wilson, who will reportedly receive $7 million over two years.
Lawson, who turns 27 next month, has started 31 of a possible 32 games over the last two seasons, tallying 13 passes defensed and 99 tackles in that span. A fourth-round pick by Detroit in 2014, he has 20 passes defensed and 141 tackles in 47 games (40 starts) across four NFL seasons.
Wilson, who turns 28 on Monday, joined the Lions as a free agent two years ago after spending the first four years of his career with the New England Patriots. He has three interceptions, four passes defensed and 142 tackles across 25 games (23 starts) in Detroit.
A second-round pick by the Patriots in 2012, Wilson has eight interceptions, 14 passes defensed and 218 tackles through 79 games (27 starts) across six seasons.
