Terence Newman will miss the remainder of the preseason but be back in time to play against the New York Jets in the season opener, according to a post made by the cornerback on Twitter.
"A little groin pull and be back for the jets!," Newman tweeted. "The man upstairs has my back and I have his. Thanks for the encouragement. Have a good night."
Newman left the field favoring his right groin late in Wednesday's practice at the Alamodome. For the final team portion of the practice, the Cowboys were without both their top cornerbacks, as Mike Jenkins also sat out contact drills after suffering a stinger on Tuesday.
Newman later underwent tests to determine the severity of the injury.
A model of durability his first four seasons with the Cowboys, the second half of Newman's career to this point has taken a toll. He missed the beginning of the 2007 season with a foot injury and only started 11 games that year.
In 2008, Newman suffered a slight tear in his groin near the start of training camp and missed all of preseason and the regular season opener. He returned but was still affected by the injury, and eventually missed fived games with what was finally diagnosed as an abdominal strain.
The cornerback had a clean bill of health in 2009 and played every game in 2010, though his play was negatively affected down the stretch when he was forced to take pain-killing injections to overcome a rib injury.
Orlando Scandrick will replace him with the starters for the time being. Restricted free agent Alan Ball, who can begin practicing tomorrow, could fill in as the third cornerback, or second-year pro Bryan McCann.
The Cowboys have several players dealing with injuries at the moment, but Newman's is the most serious injury setback since camp began.
