NEW YORK - Terry Francona was being treated for chest tightness while his team headed to Toronto, and it's uncertain when the Red Sox manager will return to the dugout.

Forced into a New York hospital for a variety of tests Wednesday morning, Francona had to listen on the radio to the Red Sox's ninth-inning rally against Mariano Rivera and the New Yankees for a 7-3 victory, their first win as World Series champions.

"His blood pressure returned to normal since the ninth inning," Red Sox spokesman Glenn Geffner said. The team would not specify what Francona was tested for or any results.

Yankees captain Derek Jeter also was taken to a hospital Wednesday. After being hit in the helmet by a pitch in the eighth inning, Jeter went for a precautionary CT scan. The results were normal and Jeter was expected to play Friday night against Baltimore, the Yankees said.

Francona, who turns 46 on April 22, was transferred back to Boston late Wednesday, the team said. He will remain under evaluation by Red Sox medical director Dr. Thomas Gill, a staff surgeon at Massachusetts General Hospital. The Red Sox would not confirm if Francona was admitted there.

"We're pleased he's coming back to Boston tonight. He's still undergoing some tests, we understand he has not had a heart attack," team president and chief executive Larry Lucchino said at Fenway Park, where the red carpet ceremony for the premiere of the movie "Fever Pitch" took place. "The tests will continue, but the victory today I know helped his morale."

The Red Sox open a weekend series against the Blue Jays on Friday and most of the team flew to Toronto after the game. Captain Jason Varitek, Tim Wakefield, Kevin Millar, Johnny Damon, Trot Nixon and David Ortiz attended the premiere.

"I'm thinking about him. I think he's going to be getting better," Damon said. "He's being treated by the best doctors in the world."

Francona, who had life threatening blood clots in 2002, began his day by taking the 8 a.m. bus to Yankee Stadium with the coaching staff. Upon arrival, he said he wasn't feeling well but continued with his routine, even fulfilling media obligations.

Around 9:30 a.m. he was taken by ambulance to New York Weill-Cornell Medical Center. Head trainer Jim Rowe accompanied Francona to the hospital, then returned for the game. Gill monitored his treatment by telephone.

"He just felt a little tightness in his chest," acting manager Brad Mills said before the game. "He was a little concerned, there's no doubt. He told me, `Don't worry about me. I'm going to be OK.'"

But Mills, friends with Francona since they were roommates and teammates at the University of Arizona said, "I'm going to worry about you."

General manager Theo Epstein informed the team of Francona's situation in a very brief meeting after the second Red Sox bus arrived around 10:30. He then went to the hospital and spent the game with Francona.

Players asked trainers for updates during the game, but Damon said they "weren't given any until after."

Francona had an unimpressive 285-363 as manager of the Philadelphia Phillies from 1997-00 and came to Boston with a reputation for being too nice and letting players take advantage of him. But the Red Sox responded to his easygoing personality and jelled into a raucous bunch that brought Boston its first World Series title in 86 years.

"Tito has meant so much to this whole team," Damon said. "He's the guy that would go to battle for you."

Down 3-2 heading into the ninth inning, Boston scored five runs off Rivera, who has blown saves on consecutive days.

"I almost needed a bed next to Tito," Mills said jokingly of the tense game. "(The win) was a lot to do with the guys focused on what they have to accomplish."

The Red Sox were upbeat after their ninth-inning comeback, yet there was little of the boisterous revelry common from the team that dubbed itself Idiots during the playoffs last season.

First baseman Millar, though, found it easy to crack a smile after hearing his manager was doing well.

"We're all doctors," Millar said. "The first two days we tightened up his chest and today we lowered his blood pressure."

Francona experienced chest pains before, a result of blood clots that developed from a knee operation.

Ten days after knee surgery in 2002, he was in Seattle interviewing for the Mariners' managing job when he experienced severe chest pains.

Upon his return home, Francona said, doctors discovered a blood clot had gone to his lungs. He was given blood thinners and the problem was thought to be under control, but complications developed. He had staph infections in both knees, which required four more operations, he said, and then developed serious hemorrhaging in his leg that ultimately required an additional two operations.

He was sent home after Thanksgiving, but more clotting ensued and he was hospitalized until Christmas Eve. In all, he said, he underwent eight operations to deal with the problem. On more than one occasion, he said, the situation was life-threatening.

Francona played 10 years in the major leagues as a first baseman and outfielder. He had already had 11 knee operations when he went in for the arthroscopic procedure in November 2002.
