Smith sprained his right shoulder during the Chiefs 34-7 victory over the St. Louis Rams last Sunday, but will start against the New York Jets this weekend.
"The last two days have been great," Smith said Wednesday. "I’ve got great work in, and I expect the same (Wednesday)."
Covitz reports that the quarterback "seemed to throw effortlessly" during the portion of practice that was open to the media.
Smith said he received treatment on his shoulder both at halftime of and after the game against the Rams.
"I didn’t want to make a big deal of it. I felt like it was something I could handle," he said. "I’ve had a history of stuff with my right shoulder. I was a little sore, but I felt good, though."
Smith has completed 144-of-215 passes for 1,493 yards with nine touchdowns and four interceptions this season.
The Chiefs (4-3) host the Jets (1-7) on Sunday.
