Fresh off of signing a massive contract extension, Los Angeles Clippers forward and Mayor of Lob City Blake Griffin has injured his knee at a United States National Team scrimmage and will undergo an MRI. He will miss the team's exhibition game tonight against the Dominican Republic.

Griffin is heading back to Los Angeles to be examined by the Clippers' medical staff after his knee reportedly experienced swelling after the injury occurred.

Number one overall pick in this year's NBA Draft Anthony Davis has been called in to replace Griffin at training camp and is expected to dress for the US for tonight's game. He may end up replacing Griffin on the Olympic roster, as the Clippers may not want Griffin to risk injury and return to the team after signing a 5 year, $95 million contract extension. Davis is listed as one of six alternates for the US Olympic squad and would be the most logical replacement for Griffin based on his position.

UPDATE 11:12 p.m.: Griffin has suffered a torn meniscus and will miss the Olympics, but should be ready for the regular season.
