Josh Allen appeared to be knocked out cold on hit by Jonathan Jones

Buffalo Bills quarterback Josh Allen was on the receiving end of a brutal hit to the head from a New England Patriots defender on Sunday, and it appeared to leave him unconscious for a few moments.

Allen scrambled for a first down in the fourth quarter before Patriots cornerback Jonathan Jones leveled him with a helmet-to-helmet hit. Allen laid motionless on the turf for a few seconds, but he was eventually able to get up and walk off the field under his own power.

Matt Barkley took over for Allen, who went to the blue medical tent on the sideline before jogging to the locker room. He was likely placed in concussion protocol.

The hit from Jones will almost certainly draw a fine from the NFL, and he is fortunate he was not ejected from the game. We saw Vontaze Burfict get ejected earlier in the day on a similar play, so Jones probably should have been tossed as well.
