PHILADELPHIA -- Mets shortstop Jose Reyes is scheduled to leave the club on Wednesday afternoon for a three-game rehab assignment that will begin the following day.

Though no more committal about the schedule than he was earlier in the week, Mets manager Terry Collins did divulge more details of his shortstop's assignment: Reyes will play at Double-A Binghamton on Thursday, Friday and Saturday, rest Sunday and join the Mets for half of their Monday doubleheader at Citi Field.

"It can all change if he wakes up tomorrow and his leg is stiff," Collins said Tuesday afternoon. "But he's already done his training today, his workout today and he feels great. So I think it's all a go."

On the disabled list since Aug. 8 with a strained left hamstring, Reyes was batting a league-leading .336 with five home runs and 34 stolen bases prior to his injury. Though Reyes lobbied to start both games of Monday's doubleheader against the Marlins, Collins has already nixed the idea.

Pagan's stomach issue could be linked to colitis

PHILADELPHIA -- Mets manager Terry Collins believes the digestive issue that forced Angel Pagan out of Monday's game was a symptom of colitis, the disease from which Pagan has suffered for nearly a decade.

"It's no joke," said Pagan, who was not convinced that Monday's episode was directly related to his condition. "It's something that's going to be with me for the rest of my life."

Battling digestive problems as far back as 2004, Pagan spent two months on the disabled list with colitis in '07, missing 50 games. It was then that he began taking the medication that he still uses today, and will continue to use for the rest of his life.

"It's scary, because when you have a disease that's going to be with you your whole life, you don't know what it's going to turn into," Pagan said. "I'm very thankful now that they know how to control everything and I know how to take care of everything myself. I'm a little more calm about it."

Pagan's colitis, which inflames his digestive tract, may or may not have been the direct cause of his stomach problems in Monday's game. Collins believes it was, removing Pagan in the fifth inning after he nearly missed an at-bat while using the restroom.

"It doesn't happen very often," Collins said of his center fielder's symptoms flaring up. "But when it does, it's an emergency."

Collins' hometown near earthquake's epicenter

PHILADELPHIA -- Terry Collins was enjoying lunch on Tuesday when he felt the rumble of the magnitude-5.9 earthquake that shook much of the East Coast. His thoughts immediately went to his house in Midlothian, Va., roughly 50 miles from the quake's epicenter near Mineral, Va.

"I'm trying to find out if it's cracked in half or not," Collins said of his fruitless efforts to reach anyone in his hometown.

Collins' earthquake experience was certainly unique for the Mets, most of whom were already at Citizens Bank Park and unable to feel its effects. Though ballpark staff evacuated the building on Tuesday afternoon, the Mets never received word of the evacuation and -- unaware of the quake -- remained rooted in the visitors' clubhouse.

"Some people said we were on the bus," outfielder Jason Bay said. "Some people said we were walking here. I have no idea. I never felt it."

The Phillies released a statement later Tuesday afternoon revealing that they had completed a check of Citizens Bank Park, discovering no damage.

Tejada matching glovework with offense

PHILADELPHIA -- With production comes reward. So it went Tuesday for Mets shortstop Ruben Tejada, who graduated to second in the lineup on the strength of a recent hot streak at the plate.

"Right now, he's putting as good of at-bats together as anybody in the lineup," manager Terry Collins said. "We're having a little problem pushing runs across, so I'd like to get some guys up there that are swinging good."

In addition to his strong defensive play, Tejada is hitting .421 with seven walks over his last 12 games, ranking fifth in the Majors in batting average and on-base percentage over that span. Given that production, the Mets have already discussed the merits of starting Tejada at second base once Jose Reyes returns from the disabled list next week.

As promised, Collins also started Lucas Duda in right field Tuesday and Nick Evans at first base, in an attempt to give Duda more outfield exposure heading into next season.

Worth noting

• Left-hander Johan Santana (recovery from left shoulder surgery) was scheduled to resume throwing off a mound Tuesday in Port St. Lucie, Fla. With little more than a month remaining in the season, however, it is highly unlikely that Santana will return to the big leagues this year.

• The Mets have announced that they will host a motivational program with 17-year FDNY veteran and 9/11 First Responder Matt Long prior to Saturday's game against the Braves at Citi Field. Long will discuss his battle to recover from a nearly-fatal bicycle accident in 2005, his experience finishing the 2008 New York Marathon and his plan to participate in the 2011 World Police & Fire Games, which begin Friday in New York City. Tickets, which include admission to Long's 1:15 p.m. speaking engagement and a copy of his book, "The Long Run," are available at mets.com/mattlong.
