NASCAR returns to Texas Motor Speedway this weekend, and once again, the main event is on a Saturday night. The 2012 Samsung Mobile 500 will be held Saturday night at 6:30 p.m. CT from Texas Motor Speedway -- and Greg Biffle will be looking to expand on his Sprint Cup standings lead.

Biffle currently sits atop the Sprint Cup standings with 226 points, just a mere six ahead of Dale Earnhardt Jr. Many eyes will likely be on Dale Junior this weekend, as the Texas Motor Speedway was the site of his first-ever NASCAR series victory.

Still, it's very early in the Sprint Cup Series standings, as six drivers are within 24 points of the lead. Defending Samsung Mobile 500 champion Matt Kenseth is tied for third in the standings, along with Tony Stewart, Kevin Harvick, and Martin Truex Jr. The four drivers are just 12 points off of Biffle's lead.

Denny Hamlin and Ryan Newman are 16 and 24 points back respectively.
