Flowers left Sunday's game against the Chiefs with a head injury and is questionable to return, the San Diego Union-Tribune's Michael Gehlken reports.

Analysis:

Flowers left the game with what looked like a possible head injury in the second quarter, but he re-entered the contest, after going through some tests with the trainers on the sideline. However, when the Chargers took the field in the second half, Flowers was on the sidelines without a helmet and eventually headed back to the locker room. This has all the appearances of a concussion.
