Dallas, TX (Best E Casino) - Dallas Cowboys Pro Bowl cornerback Terence Newman may reportedly need surgery for a sports hernia, and could miss six weeks after the procedure.

Newman missed Dallas' win over the Cincinnati Bengals on Sunday with what was originally thought to be an abdominal strain. The Dallas Morning News reported Thursday that the team has sent Newman's MRI results to Dr. William Meyers, a top sports hernia specialist, to be examined.

This has already been an injury-marred campaign for Newman, who missed most of training camp and the season opener with a groin injury.

After missing parts of the first four games last season with a partially torn plantar fascia, Newman recorded 50 tackles and four interceptions, and earned his first career Pro Bowl selection.

Newman, in his sixth year in the league out of Kansas State, has 16 interceptions and one defensive touchdown in 80 career games for the Cowboys.

The 4-1 Cowboys travel to Arizona to take on the 3-2 Cardinals this Sunday. Newman may be sorely missed for a secondary that will try to contain the NFC's top-rated passer -- Kurt Warner -- and his star wideout Larry Fitzgerald, who ranks second in the NFL with 467 yards receiving this season, on 31 catches with four touchdowns.

Adam Jones is expected to replace Newman in the base defense, while rookie Orlando Scandrick will fill in on the nickel package.
