CHARLOTTE, N.C. (AP) — -

Penske Racing has signed Brad Keselowski and Miller Lite to contract extensions through the 2017 season.

It's the second contract extension for the defending Sprint Cup Series champion in less than two years. Keselowski signed an extension after the 2011 season that ran through next year. That contract was redone to put the driver and sponsor in concurrent deals.

Miller Lite is extending a partnership with Roger Penske that spans more than three decades. The beer brand has been the primary sponsor in NASCAR of Penske's flagship No. 2 since 1991.

The new contract covers just 24 races instead of the full 36-race schedule Miller Lite had always sponsored. Penske and MillerCoors chief marketing officer Andy England say the 12-race giveback was at Penske's request.
