Doubters emerged when 35-year-old wide receiver Reggie Wayne went down last season with a torn ACL in Week 7.

But Wayne, who isn’t participating in the team's OTAs, has conducted some workouts privately, which Andrew Luck -- the Colts’ third-year quarterback -- has witnessed. It’s safe to say Luck came away impressed.

"His attitude is awesome," Luck said, via ESPN.com’s Mike Wells. "He's around, he's coaching, he's talking football. I feel like I know Reggie. He's going to be back better than ever doing things that the 35-plus-years-olds shouldn't be allowed to do on this earth. He's a freak."
