The Patriots, as an organization, are upset with the situation because they were clear that they wanted Brady's surgery done under the direction of doctors of their choosing in Boston, sources told ESPN.
Instead, Brady opted to have the surgery in California by a doctor his family preferred, and now there are major problems. Brady was supposed to be back in New England by now, but a timeline for his return remains unclear.
Brady recently acknowledged on his Web site that doctors went in "to clean and to test the wound" on Oct. 15 because of the infection. The New England Patriots quarterback has had two more similar procedures since then.
If the infection is not brought under control, the patellar tendon graft used to replace Brady's anterior cruciate ligament could become compromised.
