Daily fantasy sports operator DraftKings has made a teeny-weeny change, but it’s one that has a potential to gain greater traction in the near future.

Last week, the DFS operator decided to remove a feature called late swap for its NBA contests. Based on the name itself, late swap allows users to remove a player from their lineups—as long as his game hasn’t started yet—and replace him with another player, whose game also hasn’t started yet.

But with DraftKings’s announcement, which will take effect on October 18, “all lineup selections will lock at the start of the contest (i.e. you will no longer be able to swap players after contest lock).”

“This change will allow our customers to enjoy the games and follow their teams rather than monitoring for late breaking news leading up to tip-off of each game,” the DFS operator said.
