"Indianapolis Colts running back Joseph Addai normally isn't a fan of standing on the sideline during football games, but Sunday he often was content to be there.

After all, the NFL's top tailback was at work at Lucas Oil Stadium, and Addai wanted an eyeful of Tennessee's Chris Johnson.

"I can't lie. I'm a big football fan first, so when I see him run, I get excited," Addai said.

Johnson got a show from Addai, too, and he was a big reason the Colts scored a 27-17 victory. Addai had two pile-pushing touchdown runs and several wiggles through tacklers for key first downs.

Addai also delivered a couple of memorable catch and runs, including a 9-yarder in the second quarter that preceded his second score and a 14-3 lead.

Peyton Manning noted how Addai, who is carrying the Colts' backfield load as rookie Donald Brown deals with a chest injury, continues to have spotlight moments when he's on the field.

"That third-and-1 that we got (in the second quarter), the guy kind of hit him in the backfield, and he broke it to get the first down just like he did last week (against Houston)," the Colts quarterback said. "Then, we're backed up on our own 1 (in the third quarter) -- a potential safety -- and he broke out of that.

"The third-down conversion for a catch going into the flat (in the fourth quarter), it all speaks to his versatility.""
