The feelings about Jason Bay within the clubhouse differ greatly from those of many Met fans. His teammates let that be known after the snake-bitten outfielder was injured yet again trying to make a difficult play.

Bay wobbled off the field after crashing his head into the outfield wall in the second inning Friday night, and the Mets never recovered from Jay Bruce's inside-the-park home run in a 7-3 loss to the Reds at Citi Field.

The Mets announced that Bay had left the game with "a possible concussion" less than two years after he suffered a season-ending one in July of his first season with the Mets in 2010. That also came in a wall collision, at Dodger Stadium.

"Because he's had this in the past, this becomes a pretty serious thing," Terry Collins said. "I felt terrible for Jason. As he always does, he plays the game one way, all out. Never backed off anything, didn't back off the wall, didn't back off the broken rib. He still dove and played the game the only way he knows how."

Bay's nearly 2½ seasons in New York have been inundated with injuries and lack of production since he signed a four-year, $66 million contract as a free agent in 2009.

Bay was appearing in just his 22nd game this season; he suffered a rib injury while diving for a ball in left field on April 24.

He entered Friday's game just 2-for-25 since coming off the disabled list on June 6, although he did belt his fourth homer of the season Thursday against Tampa Bay.
