It was reported that Diehl's hip is fine, but he has a 40 percent tear of the hamstring. That could mean that the man who started 120 straight games for the Giants could join C Shaun O'Hara on the sidelines for an extended period.
Tom Coughlin announced Koets' injury Monday, saying it came as a surprise to the organization. It is likely that Koets will undergo season-ending surgery in the near future, though Coughlin did not say when that might be.
"Adam was running outside, to the right sideline right in front of our bench, and evidently caught his shoe and just twisted the wrong way," Coughlin said. "He felt good and didn't think it was anything, but with the MRIs, the ACL was shown to be an issue."
The injury, which occurred as the Giants conducted a non-scoring drive that ate up all but 34 seconds that remained in the fourth quarter, puts a dent in the line depth that came into major play in the 41-7 win over the Seahawks. As it was, the Giants had to move left guard Rich Seubert to starting center and Diehl into guard from left tackle before the game because of the continued absence of O'Hara with a Lisfranc injury.
Shawn Andrews got his first Giants start at left tackle, too. But as the game progressed, the line had to be reshuffled several times. Diehl's injury in the third quarter put Seubert back at guard and Koets in at center. Koets' injury put Seubert back at center and fifth-round rookie Mitch Petrus at guard. RT Kareem McKenzie also suffered a slightly sprained ankle, stretching the depth to the breaking point.
But the line held. Not only did it keep the Seattle pass rush off Eli Manning -- he was never sacked in a three-touchdown effort -- but the line remained physically dominant in a 197-yard rushing effort.
The question is, going forward, just how much can the line continue to adjust. Coughlin said nothing about Diehl's hamstring, reporting only that doctors had isolated the hip for examination. But the latest news means that Andrews may become a permanent fixture at left tackle. And Coughlin is hoping that McKenzie's ankle will allow him to play.
The next move will be activating Boothe from the physically unable to perform list. He has been working out since the week before the bye and appears to have done well enough for the Giants to keep him around. A decision on that is due tomorrow, but he will undoubtedly be activated.
The Giants are also waiting patiently for T Will Beatty's surgically-repaired right foot to come around. That process may have to be accelerated now in light of a potential three-man shortage in the frontal depth.
In the meantime, the Giants can only look ahead to the immediate future. They have 1-7 Dallas to contend with next week, and who knows how the Cowboys will react after Jerry Jones replaced head coach Wade Phillips with offensive coordinator Jason Garrett Monday.
With such uncertainty on the offensive front, it's hard for Seubert to think about the NFC East leaders as a bonafide playoff contender. There's just too much football left to be played.
"You go week to week," Seubert said. "Playoffs are a long ways off. We have to worry about next Sunday, and when the end of the season comes, we need to see where we're at. We've started off the season like this before, and it didn't go together, so we have to keep it going in the right direction."
