Houston Dynamo have opted against offering new contracts to a duo of experienced players.
32-year old Jamaican forward, formerly of the Colorado Rapids, made 26 appearances and scored three goals this term while 27-year old winger Driver, who started his career in Scotland with Heart of Midlothian, appeared on 34 occasions.
A trio of other players - Brian Ownby, Bryan Salazar and Anthony Arena - also had their options declined by the Dynamo.
Dynamo general manager Matt Jordan decided to exercise the option on Young Designated Player Alexander Lopez and the injury-prone Jermaine Taylor while the likes of captain Brad Davis, top scorers Giles Barnes and Will Bruin and Honduras international Boniek Garcia were all kept on.
Jordan told MLSsoccer.com: "This is the time of the year where difficult decisions are required.
"It's handled on a case-by-case basis. Some of the players are returning and some are not."
