Carl Edwards was third fastest in that session followed by rookie driver Ricky Stenhouse Jr. and Ryan Newman.

In the second and final practice session for NASCAR's second-tier division, rookie Colin Braun topped the charts with a 30.465-second lap at 177.253mph. Newman was the only driver who managed to stay in the top-5 after the first practice by being second quick to Braun.

Trevor Bayne, Reed Sorenson and Brad Keselowski rounded out the top-5 in that final practice session.

Busch dropped down to 13th fast in that session after topping the first.

The Nationwide Series drivers will qualify at 4:00pm ET today, which will be broadcast on SPEED, for tonight's Dollar General 300 event which is scheduled to broadcast on ESPN beginning at 7:30pm ET.
