"That was my biggest thing ... that there was no structural damage," Maybin said before the start of Tuesday's game against the Braves.
But as a precaution, the Padres will place Maybin on the 15-day disabled list on Wednesday with inflammation in his right knee.
The team has recalled outfielder Aaron Cunningham from Triple-A Tucson. Cunningham is expected to be at Turner Field on Wednesday for the finale of a three-game series against the Braves.
Cunningham was hitting .292 with five home runs and 42 RBIs with Tucson.
Maybin was kept out of the lineup for the fourth consecutive game on Tuesday. He said before the game that he has swelling in the bursa sac of his knee.
Maybin said the knee first started giving him trouble in a series in Colorado on May 13-15, though he's unable to pinpoint when it exactly occurred.
"I couldn't tell you," he said.
During the following series in Arizona, Maybin left a game against the D-back with what was termed patella tendinitis. He's played on the knee ever since, as it hasn't always been this much of a bother.
The news that there is no structural damage in his knee came as a relief.
"We've got to calm it down and get it right," Maybin said.
Rookie Blake Tekotte got his fourth start in as many games for Maybin in center field.
