Indianapolis Colts CB Kelvin Hayden said he doubts he’ll play in Sunday’s game.

But the Colts’ fifth-year cornerback said there was still a legitimate reason for his smile Friday — that he practiced for the first time in several weeks, and that he is sure he will play next week against the Tennessee Titans.

“I’ll be ready next week,” he said as the Colts (10-0) prepared to play the Houston Texans (5-5) at Reliant Stadium in Houston, Texas, Sunday at 1 p.m.

Hayden, who has missed the last three weeks with a knee injury, practiced on a limited basis Friday.

He is listed as questionable for Sunday.

“It felt great,” Hayden said. “When you miss so much time and you actually get a chance to get back out there, it just feels so good. Everything comes back to you — the feeling you have when you’re out there. You feel kind of lost when you’re not playing, but when you get back out there, those things all come back and it feels good.

“I just love what I do and I want to be effective at what I do. Sitting down is not something I want to do, so it’s always good to get back. Attitude does come with it.”
