Obviously nothing is a guarantee.
But the business the Cowboys made by releasing five-time Pro Bowl center Andre Gurode is partly predicated on their belief that center Phil Costa will be ready for the season opener against the Jets Sept. 11.
Costa suffered a sprained posterior cruciate ligament in his knee last week. The prognosis is two to four weeks.
Coach Jason Garrett said the early indications from his rehab is taht Costa will be ready to go for the opener. They expect him to return to practice after sitting out Thursday's preseason final against the Dolphins.
The Cowboys are similarly optimistic about veteran linebacker Bradie James (foot) and tackle Kyle Kosier (back). Both were held out of practice Monday. Neither will play against the Dolphins.
Garrett said the injuries weren't considered serious and this was an opportunity to give the two veterans a break and chance to heal their wounds for the season opener.
