"The knot is still there," Torre said. "The rest of the blood is dispersing well, but that one trouble spot is still there. He felt better, but he's still uncomfortable."
While Chacon is out, Aaron Small will continue to occupy his spot in the rotation. That leaves Ron Villone, Scott Erickson and Colter Bean to fill the long-relief duties.
"We're going to have to mix and match," Torre said. "We don't have any one guy, but we have enough with those three guys to suck up some innings."
Long will play mostly off the bench, though Torre said that he could see some playing time in left field to give Bernie Williams an occasional rest before Gary Sheffield returns from the DL.
Meeting time: Torre held a brief meeting with his team before batting practice, reminding his players that despite the abundance of injuries that have plagued the team in recent weeks, everybody has to continue playing their own game.
"It was kind of a 'Rally the troops' meeting," said one player. "He wasn't angry. He just wanted to remind us not to try to do too much, because no good ever comes of that. It all made sense."
"It wasn't a negative thing, it was just that everybody can't do a little extra, but everybody can do what they do," Torre said. "The reference was, 'We're a little beat up right now, but it shouldn't have anything to do with what we do.'"
Torre also addressed the Yankees' recent defensive woes -- 22 errors in their last 13 games, including a season-high four on Saturday -- during the meeting.
"We haven't done a good job. Knowing we're short-handed, the game is speeding up when it should be slowing down," Torre said. "[The errors are] physical, but they may be stimulated by preparation and bad decisions. Some of that could be coming from trying to overdo it. We have no one on that field who is lazy."
Torre said that he has seen players pressing at the plate as well, including Alex Rodriguez, who has struggled with inconsistency in recent weeks.
"You're without Sheffield, you're without Matsui, you're without Jason [Giambi] for a time, so Alex is going to try to take on the 3-4-5-6 spots by himself," Torre said. "You can't do that."
Deepening the depth charts: The Yankees came to terms with DH/1B Erubiel Durazo, adding another hitter with big-league experience to their farm system.
Durazo, whose best season came in 2004, when he hit .321 with 22 home runs and 88 RBIs for Oakland, will report to the Yankees' complex in Tampa on Wednesday. Durazo will play in some extended Spring Training games to "knock the rust out," according to Cashman, then be assigned to Triple-A Columbus.
New York has also been watching outfielders Richard Hidalgo and Jason Romano work out in Tampa this weekend, and Cashman expects to sign both players to Minor League deals.
Jorge still hurting: Jorge Posada was out of the lineup for the second straight day, as he was still battling tightness in his upper back. Posada first felt the spasms on Friday night before the game, though he started the game before leaving in the second inning.
Torre said it was "doubtful" that Posada could pinch-hit on Sunday, but said he could be available on Monday.
Coming up: The Yankees open a three-game series against the Red Sox at Fenway Park on Monday, as Chien-Ming Wang takes on Curt Schilling. First pitch is scheduled for 7:05 p.m. ET.
