New York Giants quarterback Eli Manning has a slightly separated shoulder which is expected to keep him out at least a month, sources told ESPN's Chris Mortensen on Monday.

Doctors told the team that Manning does not need surgery, but the quarterback will get a second opinion from orthopedic specialist Dr. James Andrews in Birmingham, Ala. After the game Sunday, Manning said the shoulder was just bruised and sore.

It was feared that Manning also had torn his labrum in Sunday night's 45-35 loss to the Dallas Cowboys, but an MRI determined that was not the case, sources said.

Giants spokesman Pat Hanlon emphatically denied that Manning had separated the shoulder and said that it was a contusion of the AC joint and he is day-to-day.

Hanlon added: "Don't be shocked if you see him playing on Sunday."

A Giant Loss
Week 1 of the '07 season was definitely no treat for the Giants. Now, they face the possibility of being with Eli Manning for the next four. Luckily for New York, three of those games are at home.

Top defensive player, end Osi Umenyiora, and the Giants' new starting running back, Brandon Jacobs also left the game with knee injuries. And backup cornerback Kevin Dockery left the game late in the third quarter with a right ankle injury.

The Giants announced on Monday that Umenyiora has an irritation to the lateral meniscus of his left knee. His status is also day-to-day and he will be re-evaluated later in the week.

Jacobs sprained the MCL of his right knee, the team said. He will be evaluated on a week-to-week basis.

The results of the MRI on Dockery's ankle were not available as of 5 p.m. on Monday.

Manning threw a 9-yard touchdown pass to Derrick Ward with 7:20 left that got New York within 38-28. After botching a 2-point try, the Giants got the ball back on Romo's only interception. Manning followed with a 10-yard touchdown pass to Plaxico Burress, their third connection of the night, to make it 38-35.

But Manning didn't return, and the Giants were out of rallies.

To bolster their depleted roster, on Monday the Giants signed tackle Russell Davis, a nine-year veteran who has played for Chicago, Arizona and Seattle.

Davis, 6-foot-4 and 310 pounds, was most recently with the Seahawks, who released him on Sept. 4. He has played in 104 games with 83 starts and recorded 348 tackles (212 solo), 11½ sacks, nine passes defensed, three forced fumbles and two fumble recoveries.
