The 25-year-old is reportedly set to move to Penske Racing to drive full time for the team next year in NASCAR's top-series, taking David Stremme's place in the leading Dodge outfit.
"I'm really not in a position to talk about any of that stuff right now," said Keselowski ahead of the Nationwide Series race at Bristol, which he started from pole.
"I'm really not prepared to address any of the rumours about next year. I'm here to race the Nationwide car and win with it tonight, and I am not going to let anything get in the way or distract us from that end."
Last year Keselowski turned down an offer to driver for Penske this season, as he was expecting to complete a part-time schedule in 2010 in Hendrick Motorsports' #5 car, sharing duties with Mark Martin.
However earlier this year, the 50-year-old veteran announced he wanted to run the full season again, leaving no room at Hendrick for Keselowski.
A week ago he said that if he were to remain with Hendrick-operated JR Motorsports in the Nationwide Series next year, he would be forced to drive for a Chevrolet team in the Sprint Cup, an option he didn't rule out.
But with all drivers staying put at Hendrick Motorsports, Dale Earnhardt Jr not keen on moving his team up to Cup yet, and Tony Stewart all but ruling out adding a third car for next year, a move to Penske looks as the best option left for Keselowski.
Back in April he scored his maiden Sprint Cup win at Talladega in just his fifth start in the series, driving for also-ran Phoenix Racing.
Meanwhile David Stremme, who was drafted in the #12 Penske car this year after a season of testing with the team, has failed to score better than a 16th place finish at Fontana, which he repeated last week at Michigan.
