NEW YORK -- Mets left fielder Jason Bay was diagnosed with a mild concussion, manager Jerry Manuel said, and was not in the lineup Tuesday.

Bay suffered the concussion on Friday while running into the outfield wall in Los Angeles. He played the next two games, going 2 for 9 with four strikeouts, then spoke up about the symptoms during the flight home from California.

"I didn't really have the headaches until the flight home," Bay said before Tuesday night's 8-2 win over St. Louis. Since then, he said, he has felt "dull headaches."

Manuel said Bay will be re-evaluated in the next two to three days.

Bay didn't think he would be out for long. "If all goes well, inside of a week," he said of his return to action. He also said he had no history of concussions.

Angel Pagan played left field Tuesday in place of Bay, who is struggling in his first season with the Mets. The three-time All-Star, who signed a $66 million deal with the Mets, is hitting just .259 with six homers.

If Bay is OK, he could soon resume baseball activities, Manuel said.

The Mets are sure to be careful with Bay's condition. In 2008, the team drew criticism from how it handled outfielder Ryan Church, who was slowed for much of the season by two concussions.

Bay was injured during Friday night's 6-1 win at Los Angeles. He made a running catch on Jamey Carroll's drive to end the second inning, and his momentum carried him face-first into the bullpen gate. Bay was down on the warning track for a few moments.

Bay later hit a bases-loaded double, then left as a precaution in the bottom of the eighth.

Over the weekend, Bay said he felt sore and stiff but had no problems playing.
