Keon Broxton left Thursday's game after being struck in the helmet with a 92 mph fastball thrown by Antonio Senzatela of the Colorado Rockies.
The Milwaukee Brewers announced after the game that Broxton suffered a slight nasal fracture but won't be placed on the disabled list.
"He avoided something incredibly serious," Craig Counsell said.
The ball struck a protective flap on Broxton's helmet. The force of the pitch appeared to push the helmet flap into Broxton's nose.
"That flap, man, that thing just saved my life,'' Broxton said. "The crazy thing about it is I was thinking about taking it off a couple days ago, too, and then this happens. I'm never taking that thing off.
"It just felt like I got punched by Mike Tyson. But other than that I feel good.''
