Quintero, who suffered a concussion and spent the night at Methodist Hospital in Houston after Dodgers shortstop Luis Maza's swing hit him, visited the Astros' clubhouse and is taking it easy.
"I just told him he ought to be real thankful it wasn't any worse," said manager Cecil Cooper. "He'll be out for awhile. I think he'll have to sit around for three or four days, and then he'll do some light walking and after that, ride the bike and stuff."
Quintero was placed on the 15-day disabled list on Tuesday, an automatic move in the case of a concussion, and was replaced by J.R. Towles in the lineup.
Cooper said Quintero did not remember what happened Tuesday night when asked who had hit him, but Quintero was able to recognize his manager and teammates.
Quintero was batting .235 with three runs on 10 hits before Tuesday's game. He had a perfect fielding percentage and had thrown out one basestealer.
