C.J. Anderson, Vernon Davis and Danny Trevathan injuries: Broncos playmakers out vs. Chargers

Two Denver Broncos playmakers were ruled out at halftime in their Week 13 game against the San Diego Chargers. C.J. Anderson suffered an ankle injury and would not return; Vernon Davis entered the NFL's concussion protocol and would not return. Ostensibly, that would mean Davis suffered a concussion.

Oddly, Anderson ran out at halftime with his teammates, helmet and everything, according to DenverBroncos.com's Andrew Mason. But he was ruled out. It wasn't obvious how Anderson became injured. Davis suffered his injury in the last play of the first half.

Look for more Juwan Thompson filling in for Anderson, and for more of Owen Daniels and Virgil Green in Davis' stead. The Broncos lead the Chargers 17-3 in the third quarter.

Update: Linebacker Danny Trevathan, who enjoyed the pick-six against Philip Rivers that put the Broncos up two scores, suffered an apparent concussion in the second half and would not return (Kubiak confirmed postgame that both Davis and Trevathan were in the concussion protocol but not confirm whether they each suffered concussions). The Broncos ended up beating the Chargers 17-3 to improve to 10-2.

Trevathan later tweeted the all-good.

I'm all good over here! Thank you all for your concern . #lionbacker
