There was nothing easy about the final stretch of C.J. Anderson‘s journey toward 1,000 rushing yards.

But on his 18th carry Sunday, as night fell on a frozen Sports Authority Field, the Broncos’ running back darted up the left side for 10 yards, officially putting him over the 1,000-yard mark for the first time in his five-year career. Anderson also became the first Denver running back since Knowshon Moreno (1,038) in 2013 to reach that plateau.

“It means a lot,” Anderson said as he sat in his locker after the game. “I was an undrafted guy. I’ve put a lot of work in, a lot of hard work. A lot of rehab coming off surgery. It’s a special place.”

The 10-yard run by Anderson, which came early in the fourth quarter, put him at 61 yards for the game and 1,007 for the season.
