Falcons coach Dan Quinn didn't put a timetable on a full return, but rookie first-round draft pick Kaleb McGary is working his way back from a heart procedure starting with participation in walkthrough. McGary underwent a third cardiac ablation procedure July 31. Now, McGary's going through the return-to-play guidelines, which means easing into individual work. He has not be cleared for full contact and won't play in Thursday's preseason game vs. Washington. McGary, when healthy, is expected to compete with veteran Ty Sambrailo for the starting role at right tackle. Quinn revealed that Sambrailo is banged up as well coming off a shoulder injury following last week's exhibition vs. the Jets. Matt Gono listed as the third string right tackle, while veteran John Wetzel listed as the backup left tackle to starter Jake Matthews.
