TALLADEGA, Ala. -- Kyle Busch will have to wait one more day to reaffirm his talents in restrictor-plate racing.

Rain postponed Sunday's Aaron's 499 race at Talladega Superspeedway moments before it was to have begun. The race has been rescheduled for noon today and will be televised by FX. The forecast calls for mostly sunny skies with a high of 77 degrees.

Today's race is the first Cup restrictor-plate event since the Daytona 500, when questions about Busch's aggressive driving arose in the Budweiser Shootout and continued in the 500. It proved to be the start of a turbulent season for the talented, but star-crossed driver.

He's had run-ins with Tony Stewart and Casey Mears and been criticized by others while scoring top-10 finishes at California, Las Vegas, Bristol and Martinsville. He ranks ninth in the season points standings.

This weekend got off to a good start for Busch, who finished third in Saturday's Busch race at Talladega. Still, Daytona clouds Busch's reputation and will until he gets through a restrictor-plate weekend without incident.

"I feel as though the only way to set that straight is to prove yourself the following weekend or the following restrictor-plate race such as today," said Busch, who starts 13th.

His reputation took a hit at Daytona when Stewart complained about Busch's driving, and their problems carried over to Las Vegas.

"The only aggression that really came out was with about 10 laps to go," Busch said of the Daytona 500. "We were running in the fourth position and I tried blocking Tony Stewart and he was already alongside me. There's a deception in your mirror that you can't really pinpoint. My left-side mirror, yeah I have it, and, yeah, I try to learn where somebody is alongside of me, but sometimes you miss. I tried blocking him and he was there.

"We'll just have to try to keep that in check this weekend, and, hopefully, we can be leading the race coming down with five to go so we don't have that problem."

Busch and Stewart talked after the incident, but the relationship remains cool. Busch hopes it can be more like his friendship with Martin Truex Jr., which came about after an incident last year as they raced for the Busch series title.

"It came down to Charlotte where we finally had a pushing match on pit road and I got under his spoiler off of [turn] two and got him loose," Busch said of Truex. "Then after the race we were mad at each other. Then the following week we talked and laughed about it and it's over, and we've had the best relationship since."

It might take Busch some time to mend any relationship with Mears, who professed his anger last weekend at Phoenix. Busch bumped Mears' car during a red flag at Phoenix in retaliation for an earlier incident.

Busch, who turns 21 on Tuesday, met with car owner Rick Hendrick after the Mears incident.

"He wanted to know exactly what was going through my head ... to further understand and try to help me out on certain circumstances that may come up in the future," Busch said.
