Frustrations mounted in the Baltimore Ravens locker room after their 40-25 loss to the Cleveland Browns on Sunday, in which they allowed the fourth-most yards in franchise history (530).

According to Mike Garafolo of NFL Network, safety Earl Thomas and defensive tackle Brandon Williams had a “heated discussion” in the training room. Thomas expressed his frustrations with the defensive tackle due to his inactive status for the game.

Thomas entered the training room as Williams was getting dressed and preparing to depart M&T Bank Stadium, one source said, adding the argument didn't get physical because players and staff members quickly interceded,” said Garafolo.

The Ravens added Williams to the injury report on Saturday morning, flagging him as questionable with a knee injury. They were hopeful that he would play on Sunday, but after a pregame workout in which he couldn't do much, the Ravens opted to hold him out of the game.

Williams is known for his run-stuffing prowess. Baltimore and Thomas clearly missed that on Sunday. The Browns ran all over the Ravens to the tune of 193 yards and four touchdowns, including an 88-yard touchdown scamper by Nick Chubb where the lane was “wide open,” as he said after the game, via Garafolo.

After starting 2-0, the Ravens are 2-2 and are behind the Browns in AFC North standings. During their two-game losing skid, they've surrendered 73 points to the likes of the Browns and Kansas City Chiefs. Ultimately, both Thomas and Williams have their fair share of issues to be frustrated upon

The Ravens will face the 0-3 Pittsburgh Steelers next Sunday.
