London (groin) was a limited participant Wednesday in his return to practice, Amna Subhan of the Falcons' official site reports.
London didn't practice at all last week and missed Sunday's 31-28 loss to the Vikings. His return Wednesday -- even in a limited capacity -- gives him some chance to suit up Sunday at Arizona, though D. Orlando Ledbetter of The Atlanta Journal-Constitution notes that London didn't look to be running full speed. Progression to full practice Thursday or Friday would indicate readiness for a return and give London his first shot to play with Taylor Heinicke as the starting quarterback instead of Desmond Ridder.
