File this within the "Take it for what it is worth" category. Kyle McLorg of Bay Area Sports guy is reporting that – according to a source – the two involved in a locker room quarrel are San Francisco 49ers T Joe Staley and TE Vernon Davis.
McLorg states that the first "tense" discussion was following the team's week 4 loss to the Green Bay Packers, which was later confirmed by head coach Jim Tomsula. Staley expressed some doubts about the severity of the knee injury that caused Davis to miss multiple games.
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.
Another verbal altercation took place following the 49ers' loss on Thursday night to the Seattle Seahawks. According to McLorg's source, this was the player argument over QB Colin Kaepernick. Staley was defending Kaepernick against Davis, who was speaking out against him.
During a radio interview earlier today, Tomsula shot down accusations of a divide within the locker room, the accusation that Kaepernick was 'alone on an island,' and compared the heated team meeting to that of an Italian dinner table.
In the five games this season that he has played in, Davis has 12 catches for 170 yards and no touchdowns.
