Munnerlyn was ranked 70th on The MMQB's Top 100 list of NFL free agents.
The 5-foot-8 cornerback is coming off his best season, when he was on a one-year contract as a member of the Carolina Panthers. He started all 16 games in 2013, posting 74 tackles and forcing one fumble. He had two interceptions, and he returned both of them for touchdowns.
Munnerlyn will be 26 at the start of next season. He's the third big loss of the day for the Panthers, who released star wide receiver Steve Smith earlier Thursday and lost fellow wideout Ted Ginn to the Arizona Cardinals.
