New York Mets third baseman Wilmer Flores left Sunday's 8-7 loss to theMilwaukee Brewersbefore the bottom of the fourth inning with lower back soreness.
Manager Mickey Callaway said after the game that Flores would fly back to New York to be checked by a doctor.
"I'm sure you guys have seen him having a tough time throwing the ball. He feels like he can't really bend over,'' Callaway said.
The Mets are traveling from Milwaukee to Atlanta for a Monday day-night doubleheader, and they will have a minor league player on standby to join them in case Flores has to go on the disabled list.
