IRVING -- Terry Glenns surgically-repaired right knee still has not passed a physical and owner Jerry Jones said Tuesday the Dallas Cowboys will wait as long as possible for the wide receiver to sign a $500,000 injury settlement -- possibly through training camp and up to the start of the season.But Jones reiterated that it was something that needs to be done if Glenn is going to get on the field in 2008.Jones said Glenns right knee -- which was operated on twice last season, keeping him out of the first 15 games -- failed a physical after the season and still has not passed.Although the Cowboys believe Glenn needs season-ending, and possibly career-ending, microfracture surgery to fully repair the right knee, Jones said the Cowboys are supportive of Glenn in his attempts to make a go of things without the surgery.From a business standpoint, however, Jones said the Cowboys cant chance Glenns $1.74 million base salary on his knee holding up. If he signs the injury settlement, the Cowboys will be obligated to pay only $500,000 if Glenn is sidelined for the season because of the right knee. If he is sidelined for any other reason, he would get his full salary."I paid him $5 million last year and we got four plays," Jones said.Jones said the Cowboys thought they were close to getting the waiver signed with Glenn a few weeks back and will remain optimistic about getting him on the field."It would surprise me if we didnt get something worked out," Jones said.
