ARLINGTON, TEX. - Dallas Cowboys quarterback Tony Romo, who suffered a fractured rib in Sunday's 27-24 overtime win at San Francisco, has been diagnosed with pneumothorax, otherwise termed a collapsed lung.
According to medical publications, pneumothorax is "the collection of air in the space around the lungs. This buildup of air puts pressure on the lung, so it cannot expand as much as it normally does when you take a breath."
The Cowboys released a statement Monday evening on Romo's health.
"Additional testing on the fractured rib of Tony Romo today revealed that he also has evidence of a pneumothorax -- a condition that is not unusual for an injury such as the one Romo sustained in the game in San Francisco," Cowboys team spokesman Rich Dalrymple said. "Varying degrees of a pneumothorax can heal in differing time frames."
The statement said that the team's medical staff would continue to monitor Romo's progress throughout the week, but nothing was mentioned about his status for next Monday night's home game against Washington.
Romo, who missed more than half of the 2010 season due to a broken left clavicle, suffered his latest injury in the first quarter against the 49ers. He missed nearly the entire third quarter while getting treatment, but came back and rallied the team to overtime, connecting with Jesse Holley on a 77- yard pass play to set up Dan Bailey's game-winning field goal.
Romo went 20-of-33 for 345 yards and two touchdowns Sunday.
Jon Kitna is listed as the second QB on Dallas' depth chart with Stephen McGee third.
