Osi Umenyiora disconcertingly missed practice yesterday with the Giants, as the pass rushing defensive end was dealing with a swollen right knee.

“Osi’s got some swelling and so we shut him down,” coach Tom Coughlin said. “It’s more precautionary than anything. He’s practiced every practice.”

Umenyiora has had surgery on both knees, undergoing a procedure on his right knee last year and his left knee in 2008. His fellow defensive end, Jason Pierre-Paul, also missed practice again yesterday with back spasms, but Coughlin said he was improving.

* Cornerback Jayron Hosley (toe) had his boot removed but did not practice, while left tackle Will Beatty (back) “did some things,” according to Coughlin. Guard Chris Snee (leg), linebackers Michael Boley (hamstring) and Mathias Kiwanuka (groin) and wide receiver Jerrel Jernigan (leg) were among those out yesterday.

* Tyler Sash was carted off the field after Coughlin said the safety’s “ankle locked up.” According to the Associated Press, Sash — suspended for the season’s first four games for using Adderall — is set to meet with NFL commissioner Roger Goodell today.

* It was originally thought Shaun Rogers was finished for the year with a blood clot in his leg, but last week Coughlin revealed the defensive tackle might be able to return at some point. Yesterday, Rogers said he feels “all right” and added the clot wasn’t life-threatening. There is no timetable for his return.

“We did a little bit more due diligence and got a little bit better prognosis,” he said. “Hopefully there’s some room left in there to get out there. We’re still in the process of making that decision.”

* Coughlin said the Giants will decide after today’s practice whether Hakeem Nicks, recovering from a broken foot, will play in Wednesday’s final preseason game against the Patriots. The Giants’ No. 1 wideout has not played in the team’s first three games.

* Undrafted rookie defensive end Adewale Ojomo, a 6-foot-4 270-pounder out of Miami, recorded two preseason sacks against the Jets and one against the Bears. Said Ojomo, “I did it the week before, I did it this past week and I’m going to do it again this week.”
