McQuistan was drafted by the Dallas Cowboys in the seventh round of the 2006 NFL Draft. In 72 career games, the tackle has made 11 starts with the Cowboys, Miami Dolphins, New Orleans Saints and Arizona Cardinals.
Baker tore his patellar tendon in his right knee in the fourth offensive series against the Houston Texans on Saturday. The 29-year-old, sixth-year veteran out of USC played just four games last season after having surgery on his patellar tendon in his left knee.
The tackle signed a six-year, $41 million deal with Atlanta last offseason.
