Patriots wide receiver Wes Welker had two catches in the team's preseason victory over the Falcons on Thursday night. Welker played for the first time since seriously injuring his knee in January. He was on the field for six plays of New England's opening drive, catching a six-yard and 14-yard pass from Tom Brady. Welker tore the anterior cruciate ligament and medial collateral ligament in his left knee Jan. 3 playing against the Texans.
