Jones' surgery not worst kind of microfracture

Posted by ESPN.com's Mike Sando

The Seahawks expect Pro Bowl left tackle Walter Jones to miss minicamps and return for training camp after undergoing microfracture knee surgery.

Some players struggle to return from microfracture surgeries, in which doctors drill tiny holes in the bones to stimulate a process that can simulate cartilage regeneration. Not all microfracture surgeries are the same, apparently, and this one might be less serious than others.

Coach Mike Holmgren to reporters: "Microfracture, by definition, is they pick it and try and create some new things in there. Where they did it, I guess where you do it, it wasn't on a weight-bearing surface, so it isn't what you and I would normally think. So, it really is going to be fine."

Holmgren on Jones: "I had the privilege of coaching one of the great linemen of all time in Walter Jones. He always gave the team and me everything he had."

Four of the five offensive linemen to start the season opener for Seattle are now on injured reserve and finished for the season.
