Osi Umenyiora, the unhappy New York Giants defensive end who just began practicing with the team on Monday, is undergoing arthroscopic surgery on his right knee the morning and will be sidelined 3-4 weeks, the team announced.
Umenyiora began training camp with a one-day holdout and had spent the first several weeks doing no more than riding the exercise bike while demanding a new contract or a trade. He then began to complain about soreness in his knee. Last week, however, doctors checked the knee and cleared him to play.
After just three practices, however, Umenyiora has opted for surgery.
Umenyiora, 29, had 11.5 sacks and 10 forced fumbles for the Giants a season ago. In his place, the Giants have last season's first-round draft pick, Jason Pierre-Paul. JPP was dominant in the preseason opener against Carolina with two sacks and a couple of quarterback pressures.
Prior to this morning's announcement the Giants had not given any indication that Umenyiora had been experiencing difficulty with the knee this week.
