Inciarte was placed on the seven-day concussion disabled list Friday.
In the third inning Thursday night, as Inciarte attempted to swipe second base, Houston's Jonathan Villar left the ground to field the throw from catcher Carlos Corporan, and the shortstop's leg made contact with Inciarte's head.
"As soon as he got me, I had blurred vision and wasn't feeling good," Inciarte said. "I thought it was going to go away quick, but during the game it kept going and I was feeling dizzy and had a headache the whole night."
Inciarte was diagnosed with a concussion and will miss a minimum of seven days. He left the team to return to Phoenix on Friday and will start taking concussion tests shortly.
With center fielder A.J Pollock out for six to eight weeks with a fractured hand, Inciarte was getting the bulk of starts in center.
"It is really frustrating," Inciarte said. "I didn't want this to happen. I don't want anybody to get hurt, but I had this opportunity and I was trying to play as hard as I could and it just happened."
