Mario Williams is no longer a Houston Texan, but he still has a lot of love for the city and is working to keep the streets safe.
Williams has donated five Dodge Chargers to the Houston Police Department.
The cars will be used for traffic enforcement and to slow down aggressive drivers.
The new cars will blend into traffic, since they are black and feature stealth decals that are not very easy to see.
Police Chief Charles McClelland presented Williams with an honorary badge on Tuesday to thank him for the donation.
Williams also donated several Chevrolet Camaros to the department in 2011.
