Both players were ejected in the first half of the Week 12 battle, but additional penalties were levied because they violated unsportsmanlike conduct and unnecessary roughness rules.
Rapoport previously reported the suspensions were likely due to the fact each player ramped up the skirmishes after things appeared to be winding down.
NFL VP of communications Michael Signora provided a full explanation of the punishment:
Raiders coach Jack Del Rio was critical of the decision on Twitter:
Both players are appealing the suspension, per Rapoport.
Bleacher Report provided video of the altercation (video contains NSFW language):
This was the second incident between these two players in the last two seasons—the last came in Week 17 of the 2016 season—with Talib ripping off Crabtree's chain both times. Still, the Broncos cornerback noted Crabtree was the one who instigated the fighting in the game.
"He punched Chris [Harris], next play he came [and] punched me," Talib told reporters Sunday. "So, I mean, so he was on whatever he was on."
Crabtree has 42 catches for 502 yards and a team-high six touchdowns this season for Oakland, while Talib has started every game and is coming off an All-Pro season for Denver.
