Texans receiver Andre Johnson, who missed plenty of the 2007 season with a knee injury, will miss the rest of the 2008 offseason workouts after undergoing arthroscopic surgery on the same bum joint.

“We went back and forth with the knee throughout the offseason,” coach Gary Kubiak said Monday.  “It wasn’t feeling the way [Andre] wanted it to feel.  So we tried to do some things, some rest and those types of things, to get it better.

“He wasn’t really comfortable coming out of [mini-camp], so we said, ‘Hey, let’s go scope it and see if there are any issues.  We want you to feel comfortable.’  Everything was fine.  They cleaned it up.  Now he feels good about it.  He’s not going to be hurt by missing some of these reps, so we’ll just get him back to 100 percent and get him ready to go.”

Johnson is expected to be at 100 percent by the start of training camp.

“Yes, it’s a concern, but at the same time, injuries happen,” Johnson said.  “You just have to do what you have to do to make those injuries better.”

Johnson is signed through 2014, and there has yet to be talk of the Texans giving up on him.  But it’s an issue that the team eventually will need to consider, if Johnson’s knee doesn’t get any better — or continues to deteroriate.  Every time a knee gets “cleaned up,” there’s less cartilage left in it.  And once the cartilage is gone, it’s fairly difficult for the guy to continue playing.
