Another NASCAR team biting dust?

Sirius XM NASCAR Radio's Sirius Speedway with Dave Moody has learned that the #71 TRG Motorsports NASCAR Sprint Cup Series team will not return in 2012. Sources close to the team say TRG will announce later this week that it has shuttered its NASCAR operation and will compete only on the Grand Am Rolex Sports Car Series in 2012.

TRG finished 36th in Sprint Cup owner points last season, and would not have been a guaranteed starter for the season-opening Daytona 500. TRG Motorsports made a total of 106 starts since joining the NASCAR Sprint Cup Series in 2009, with a pair of Top-10 finishes to its credit. Bobby Labonte claimed a 10th-place finish for the team at Talladega in the fall of 2009, while Mike Bliss finished ninth in the 2010 Coke Zero 400 at Daytona. Team owner Kevin Buckler did not immediately return a call seeking comment today. Sirius Speedway
