Taylor Mays is without an NFL team. If and when the free-agent safety is signed, he'll have to wait awhile before he can play.
The league issued a four-game suspension to Mays on Monday for violating its substance-abuse policy, NFL Media reported. Also suspended Monday was former 49ers and Seahawks linebacker Nick Moody, who also received a four-game ban.
