San Diego manager Bud Black said Cabrera was "a little sore", but that soreness was in a different spot than where the hamstring strain occurred previously.
"We're going to monitor him and hope that he can come out of it in a day or two," said Black, who noted the injury might have occurred when Cabrera stole a base on Saturday.
Cabrera, who missed 21 games in July with a left hamstring strain, has played well of late. Heading into Sunday's game, he had six hits in 15 at-bats on this road trip with two walks and two stolen bases.
Cabrera is hitting .350 in his last 10 games, and his 22 multi-hit games are tied for the team-lead with Seth Smith.
Cabrera also had a disabled list stint last season with a left hamstring strain.
