AC Milan defender Oguchi Onyewu has travelled to California for a checkup on his knee as he recovers from surgery that has sidelined him for most of this season.
Onyewu was to be examined by Dr. Bert Mandelbaum, who operated on Onyewu last Oct. 21, seven days after he ruptured the patellar tendon in his left knee during a World Cup qualifier against Costa Rica.
At the time of the surgery, Onyewu was projected to be sidelined for six months.
"He is currently working with the U.S. team's medical staff," AC Milan spokesman Riccardo Coli said Tuesday. "He is expected back in Italy at the end of the week."
Onyewu was seen at last weekend's Los Angeles Galaxy opener, watching with David Beckham, who was on loan from the Galaxy to AC Milan when he ruptured an Achilles' tendon on March 14.
Onyewu hopes to play for the U.S. at this year's World Cup. The 27-year-old appeared in just one of the AC Milan's 10 competitive matches this season before getting hurt.
