Nelson exited the Astros’ eventual 4-1 victory after taking two foul balls off of his mask while umpiring at home plate, causing a 17-minute delay in the game.

Mike Everitt will replace Nelson as the crew chief for the remainder of the ALCS, MLB announced.

Kerwin Danley took over for Nelson, but not until after all players had to be removed from the field while they waited for Danley to don the home-plate umpire gear.

The rest of the game was played without an umpire on the left-field line.

When all was said and done, there was a 17-minute delay between the bottom of the fourth and the top of the fifth.

The Astros lead the series, 2-1, after Tuesday’s victory.
