KANSAS CITY, Mo. -- NFL kickers during the preseason have missed 10 of 161 extra-point attempts from the new distance of 33 yards. Cairo Santos of the Kansas City Chiefs did his part by missing one in last week's game against the Tennessee Titans.

The 151 successful point-after-touchdowns represent 93.8 percent of the total attempts. That's down slightly from the 95.1 percent of the 33-yard field-goal attempts kickers made last year (39 of 41).

Chiefs special teams Dave Toub said he expects the success percentage to go down even more during the regular season.

"That's going to go down because of the pressure you're going to get from the field-goal block team and the pressure of actually having to make that one-point kick from a 33-yard distance," Toub said.

Because of the rule change, the Chiefs and Santos worked plenty on kicks from 33 yards during offseason practice and training camp. That didn't seem to matter on his first try against the Titans, when the kick went wide to the left.

"He pulled it," Toub said. "It's a field goal. It's a 33-yard field goal. I'm glad he got it out the way now [so] it doesn't show up during the regular season. That's the way we're looking at it. He just yanked it. We'll fix it. There was nothing wrong with the operation. The snap and the hold were all good. It was strictly Cairo.

"It's done now. He's got that out of the way."
