NEW YORK -- Ryan Church said that he felt good on Friday afternoon after running and taking some fly balls during warmups, but his return to the Mets' lineup is still up in the air.

The right fielder has been out of action since sustaining his second concussion of the season on May 20 in Atlanta. Though Church said that he feels better than he did a week ago and has gone through his light pregame routine, his return will ultimately be based on a doctor's decision.

Manager Willie Randolph wants Church back on the field, but he isn't ready to rush him back into action before he's healthy.

"We need to see him bounce around a little bit, get a good sweat going, and he'll pretty much dictate if he's ready to go," Randolph said. "He needs to say, 'Skip, I'm ready to go. I feel good.' And when he says that, we'll put him in the lineup."

When asked if he might change his style of play in order to be more cautious after his attempt to reach second base ended in a collision that caused the concussion, Church smiled.

"I might be peeling off a little earlier," Church said. "Other than that, I'm not going to change a thing. I'm still running the walls, doing what I've got to do."
