The original plan was that Chavis would return from the injured list this weekend at Tropicana Field against he Rays, but that hit a snag when he felt more discomfort in his right oblique.
"Chavis, he was a little bit sore yesterday," said Red Sox manager Alex Cora. "So I don't know. We'll talk about it in the upcoming days, but I don't think that's moving where we thought it would go. He was looking good early in the week and yesterday he felt soreness. If that's the case, we're probably going to shut him down."
Chavis hasn't played for the Red Sox since Aug. 11. His first injury was a sprained AC joint in his left shoulder. While he was coming back from that ailment in a Minor League rehab assignment, he tweaked his oblique.
In 95 games this season, the rookie right-handed hitter is slashing .254/.322/.444 with 18 homers and 58 RBIs.
Developments are more encouraging with some other position players.
Mookie Betts, who hasn't played in a week due to inflammation in his left foot, should return for this weekend's four-game series against the Rays. Betts is likely to be Boston's designated hitter on the turf.
J.D. Martinez was out of Thursday's starting lineup for the third straight game with tightness in his left groin. He is day to day.
Bochy knows how tough it is to repeat
Giants manager Bruce Bochy, who led San Francisco to World Series championships in 2010, '12 and '14, can certainly understand why the Red Sox had such a tough time trying to repeat this season.
"It's hard, because you look at the other teams and the talent on those teams -- a lot of things have to go right for you to win a championship," said Bochy. "You've got to have guys have at least their normal years, if not better years. You have to have some surprises, maybe the ball has to bounce your way, or even calls.
"But to go all the way, it's really, really difficult. Now, to do that again, I mean, it's tough."
No MLB team has repeated since the Yankees in 2000, and that doesn't surprise Bochy.
"We've been through it," said Bochy. "When you're trying to get there and you're approaching postseason or in the postseason, you're running on adrenaline. It's hard to maintain that. It is. That's one of the toughest things in this game, but we all have a job and responsibility to do that. As much as you say it, it's still tough for these players, because we play so many games.
"To get yourself up to that level every day, it takes something really special. That's what you sometimes have to remind yourself as a team, as a player, and that's what we would try to do."
Red Sox honor Bochy
Speaking of Bochy, the Red Sox honored the soon-to-be-retired skipper in a pregame ceremony. They gave Bochy a grandstand seat with the number 2,000 on the back of it. That was in recognition of Bochy earning career victory No. 2,000 on Wednesday.
Red Sox front office executive Tony La Russa, who had 2,728 career wins and matched Bochy's three World Series championships as a manager, took part in the ceremony. So, too, did Cora.
