Von Miller missed practice Wednesday with an illness.

He explained what happened after returning to practice Thursday.

Miller ate mozzarella sticks while watching Star Wars: The Force Awakens on Tuesday night. He felt sick midway through the film, and he fell asleep before its conclusion.

He was still too sick to practice the next day.

“You can’t put regular gas in a Ferrari,” Miller said after practice, according to USA TODAY’s Lindsay Jones. “I learned my lesson.”

Miller recorded 11 sacks for the Broncos his year. He was part of a Denver defensive unit that led the NFL with 52 sacks during the regular season.

Since being drafted second overall by the Broncos in 2011, Miller has averaged .83 sacks per game. In his fifth season, he already ranks fifth on the team’s all-time sack list with 60 quarterback take downs.

Denver will host the Steelers in the Divisional Round of the playoffs on Sunday.
