Ten months ago, Kiko Alonso suffered a torn ACL that cost him the entire 2014 season with the Bills. In the time since then, Alonso has been traded to the Eagles — and has healed so fully that he surprises himself with how good he feels.

“I honestly didn’t think I’d be doing this much,” Alonso told Philly.com at Eagles’ OTAs. “I’ve just been going on how I feel, and it’s feeling really good.”

Part of the reason Alonso feels good is that he’s running without a knee brace.

“I feel comfortable without it,” Alonso said. “I never really liked wearing the brace.”

Alonso played for Eagles coach Chip Kelly at Oregon and knew that Kelly does everything at a fast pace and has a demanding conditioning program. Still, Alsonso didn’t realize just how hard he’d be going this offseason.

“I knew what to expect, but I definitely thought I’d be more in shape, but I was wrong,” Alonso said. “I remember when I was in Buffalo, I was like I can’t imagine going against the Eagles and that pace. Because if you don’t practice like that and you go, it’s brutal.”

That brutal work in May will pay off for Alonso in September, when he finally gets back on the field after his knee injury cost him a season.
