SAN DIEGO -- Matt Stairs limped around the home clubhouse at PETCO Park on Friday with his right knee heavily wrapped in ice.
The knee, he said, felt about as good as it looked.
The Padres placed the 42-year-old Stairs on the 15-day disabled list, retroactive to June 7, prior to playing the first of three Interleague games against the Mariners at PETCO Park.
The Padres recalled outfielder Aaron Cunningham from Triple-A Portland to take Stairs' place on the 25-man roster.
Stairs has had four different surgeries on his right knee in his career, the most recent coming in 1992. Stairs said he suffered the injury in a game on Sunday in Philadelphia.
"It's nothing major," Stairs said. "I hit a fly ball to right field, and I was going around first and I hit the bag wrong and twisted it. It's sore to walk on, so we figured I would go on the DL and get healthy."
Stairs had an MRI done on the knee earlier Friday. The results, according to manager Bud Black, wouldn't likely be known until after the game at the earliest.
Stairs, who is hitting .191 with one home run over 47 at-bats, last appeared in a game on June 6.
"We wanted to give him a few days to see if it quieted down," Black said of why Stairs wasn't placed on the disabled list as soon as he suffered the injury.
