Jones suffered a twisted right knee and sprained right ankle Sunday in Atlanta’s 6-5 loss to San Francisco, the Braves’ third setback in four games.
Jones was injured after his spikes appeared to get caught in the soggy field at AT&T Park in the eighth inning. Grabbing his right knee as he fell, Jones said he first thought he had torn his anterior cruciate ligament.
Jones suffered a torn left knee ligament in 1994 that kept him out for the season.
“We just have to wait and see how the pain is the next couple of days,” Jones said while wearing an air cast on his ankle, but no knee brace. “Right now I feel the ankle took the brunt of it.”
Jones, who appeared in just 109 games last season, is hitting .238.
Atlanta (3-4) also is expected to be without second baseman Marcus Giles, who left in the seventh inning with sore right quadriceps.
Besides injuries, the Braves also have had trouble with their normally reliable starting pitching. Atlanta’s starters have posted a 10.09 ERA thus far.
After coming out of the bullpen in his first two appearances, John Thomson will start in place of Horacio Ramirez, who left after just three innings in Wednesday’s 9-8 loss to the Los Angeles Dodgers with a strained left hamstring and was later placed on the 15-day disabled list.
Thomson, who missed nearly three months last season with a strained tendon in the middle finger of his pitching hand, is 7-4 with a 2.66 ERA in his career against Philadelphia.
Philadelphia (1-5) also has gotten off to a slow start this season, losing its first four games before splitting a doubleheader Sunday against the Dodgers, winning the opener 6-3 while losing the second 6-2.
Bobby Abreu gave Philadelphia its first win of the season after launching a three-run homer with two out in the bottom of the ninth.
“That homer meant a lot for us,” Abreu said. “Losing five straight can get in your head. When you win your first game, it’s a relief for the team and that’s what we’re looking for right now.”
That win helped Philadelphia avoid its worst start in 72 years.
The relief was short-lived as Los Angeles’ Brad Penny allowed only one run through seven innings in the second game.
“We’ve played sloppy at times, and it’s come back to bite us, but you have to try and look on the bright side,” new center fielder Aaron Rowand said. “It’s better to go through a stretch like this early and try to right the ship.
“If we dwell on what’s happened so far, we’re not going to be fully into Monday.”
Brett Myers will try to get the Phillies back into the win column. He did not get a decision in his first start this season after allowing three runs and five hits over five innings Wednesday in a 4-3 loss to St. Louis.
Two of Myers three career wins against the Braves have come in Atlanta.
Shortstop Jimmy Rollins has five hits in 12 at-bats since his 38-game hitting streak ended Wednesday. He had 11 hits, including five doubles, in 42 at-bats last season in Atlanta.
