Daniel signed with the Kansas City Chiefs on March 12, 2013.
For 2013, he was secured as the backup to Alex Smith.
In Week 14 of the 2013 NFL season, Daniel played in the game against the Washington Redskins and was 1 for 3 in passing with an interception.
The Chiefs won that game 45–10.
In Week 17, with the Chiefs locked into the #5 seed in the playoffs, Daniel started his first ever regular season NFL game, a 24–27 overtime loss to the San Diego Chargers, going 21/30 for 200 yards and one touchdown pass, while rushing for an additional 59 yards.
His final 2013 stats were 248 yards, one touchdown, and one interception.

Daniel returned to the Chiefs for the 2014 season as Smith's backup.
Before week 17 against the Chargers, it was announced that Smith had suffered a lacerated spleen and would miss the game and possibly the playoffs, giving Daniel the start on Week 17 for the second straight year.
This time, Daniel led the Chiefs to a 19–7 victory over the Chargers.
The victory eliminated the Chargers from playoff contention.

Daniel remained with the Chiefs in the 2015 season but appeared in relief in only two games in the regular season and the 30–0 victory over the Houston Texans in the Wild Card Round of the playoffs.
