CHICAGO -- He's just not there yet.
Cliff Floyd, who has not played this season because of shoulder and knee injuries, continued to rehab Tuesday at Wrigley Field, where he used to play for the Cubs. Floyd said he hopes to start a Minor League rehab assignment maybe next week.
His right shoulder, which he injured in Spring Training, is OK. It's his right knee, from which fluid was drained in April, that still bothers him.
"It's tough," Floyd said. "Every time you feel like you get close, you get to a point where it flares up on you, and that's what you don't want."
Floyd has been running for nearly a week, and he started to swing a bat earlier in the road trip at Houston. But he feels pain in his knee when he pushes himself, which simply means he's not ready to go.
Padres manager Bud Black is eager to use Floyd, who signed as a free agent in the offseason. Floyd, 36, has 233 career homers and a .483 slugging percentage in 16 seasons.
"He's a definite weapon," Black said. "A long ball threat. We hope that he's making the gradual progression to accept an assignment to go out on a Minor League rehab. He's hitting and running. Once he's healthy -- and he's not quite there yet -- we'll send him out, and he'll play."
