SAN DIEGO -- The chilly weather in San Francisco didn't help Logan Morrison's right knee.
All season the Marlins have closely monitored the outfielder's knee, which required surgery last December.
Morrison was not in the starting lineup in the series opener at San Diego on Friday night, and he likely will be given Saturday off as well, since the Padres are starting left-hander Clayton Richard.
Morrison's knee acted up on Thursday in San Francisco. Morrison was removed in the seventh inning, but it was for defensive reasons. Bryan Petersen went to left field as part of a double-switch.
"LoMo was a little sore yesterday," manager Ozzie Guillen said. "We're going to continue doing what we're doing -- give him a couple of days. Tomorrow, it's going to help because they're throwing a left-handed pitcher. We're going by ear."
Greg Dobbs started in left field and hit cleanup in place of Morrison on Friday night.
The Marlins have been giving Morrison periodic days off, especially not starting him the day after traveling.
"I don't want those guys playing hurt and getting worse," Guillen said.
