Last year, Henderson agreed to a pay cut back. He also finished serving out a 10-game suspension, which stemmed from a substance abuse violation, last year.
A few months ago, Henderson agreed to a pay cut back on June 22 as part of a contract renegotiation.
Henderson was testing the free agent market for the first time in his NFL career.
In 2017, Henderson was limited to being active for seven games for the Bills.
