The first instance occurred on the Tuesday following the Week 4 loss to the Packers. The conflict apparently stemmed from Staley’s doubts regarding the severity of Davis’ knee injury, which he sustained in the Week 3 loss to the Cardinals. According to the source, on the day after the Packers loss, Davis was told by a trainer that there was nothing wrong with his knee. Staley called Davis out on this the next day and they exchanged words over it. Davis didn’t play in either of the 49ers’ Week 4 and 5 losses to the Packers and Giants.
The next altercation occurred in the locker room following last Thursday’s loss to the Seahawks. While the details of this skirmish are unclear, a source told me that this was where the players were arguing over Kaepernick. The source couldn’t clarify what was said, but told me that it was Davis who spoke out against Kaepernick, and it was Staley who defended his quarterback.
