Jim Harbaugh

Jim Harbaugh (illness) returned to the sidelines for Week 6 against the Broncos.

Harbaugh returned, walking under his own power. He appears to be okay for now and will hopefully remain well for the rest of the game. Update: The broadcast tells viewers Harbaugh is dealing with arrhythmia, or an irregular heartbeat. It sounds like this is an issue Harbaugh has managed for some time.
