In spring training on Sunday, Flores fouled a ball off the tip of his foot, but X-rays came back negative and it was diagnosed as a bruise, which is why he's confident he'll be able to return to the lineup soon.
Flores was restricted to a walking boot on Sunday, but was not wearing it on Monday.
"I'm not worried at all," Flores said about Opening Day being in jeopardy. "I hope it will just take a few days. That's it."
"It was bad yesterday. I couldn't even walk on it," Flores said. "... I'm just going to go day by day, I guess. It's a little bit swollen. I'm having a problem walking right now. I'm just going to go day by day and we'll see how it goes. It is worse than I thought yesterday. It got me pretty good."
Flores is entering his third season with the Mets. Last season, he appeared in 78 games, batting .251 with six home runs and 29 RBI.
The Mets will open the 2015 season on April 6 on the road against the Washington Nationals.
