The Kansas City Chiefs said Monday that Alex Smith didn't suffer a concussion in Sunday's win over the Indianapolis Colts despite the quarterback being ruled out in the third quarter after a second big hit to his head, according to Terez A. Taylor of The Kansas City Chiefs.

Smith underwent the concussion protocol twice against the Colts, returning briefly before being hit in the head on a designed run. He was ruled out, and it was assumed it was because he'd suffered a concussion.

However, Chiefs head athletic trainer Rick Burkholder said Monday that Smith isn't dealing with a concussion, and he was ruled out because he was in the middle of the protocol, adding he passed both times, Taylor reported.

Burkholder said Smith isn't showing any symptoms, but he'll see an independent neurologist before being cleared to return. If he is, he could practice Wednesday and start in Week 9, according to Adam Teicher of ESPN.

There was confusion in the Chiefs' postgame press conference, as head coach Andy Reid said Smith passed both protocols, but was corrected by a spokesman.

Burkholder said that was his mistake.

"The only mistake was me telling (the spokesman) concussion, out," Burkholder said, according to Taylor, adding that he thought the process "working flawlessly" aside from that error.
