SANTA CLARA -- The hit that knocked 49ers tight end Vernon Davis out of Sunday's game with a concussion drew three penalty flags. But it did not draw a fine from the NFL office.
The NFL did not fine Seattle Seahawks safety Kam Chancellor, a league spokesman said. In essence, the NFL exonerated Chancellor of any wrongdoing. Chancellor was penalized for a personal foul on that play in which he broke up a pass intended for Davis in the first quarter.
In fact, 49ers right tackle Anthony Davis was the only player in the game to be fined. He was docked $10,000 for "unnecessary roughness for striking an opponent late," a league spokesman said.
Davis was penalized and fined for a personal foul against Seattle rookie cornerback Jeremy Lane late in the game. Davis, who outweighs the defender by more than 130 pounds, knocked Lane down and hit him again while he was still on the ground after a run play that went the other direction.
The league did not fine Seahawks players on two plays in which 49ers players were injured.
Three separate officials threw flags immediately after Chancellor's hit on Davis, who ran a wheel route down the right sideline. Davis had his hands on Colin Kaepernick's pass, but Chancellor's big hit dislodged the ball.
Referee Bill Vinovich announced the infraction as a "hit on a defenseless receiver." Chancellor's shoulder appeared to strike Davis' chest area, causing Davis' head to snap backward.
Davis sustained a concussion and did not return to action. He received clearance from an independent neurologist and 49ers team physician Dr. Dan Garza to return to physical activity.
He resumed non-contact practice on Thursday, and must perform contact simulation to gain final clearance to play Sunday against the Arizona Cardinals at Candlestick Park in the regular-season finale.
Seahawks linebacker Leroy Hill was also not fined for his low hit on 49ers receiver Mario Manningham while teammate Jeremy Lane had Manningham wrapped up. Hill went in near knee level on Manningham, who sustained season-ending torn knee ligaments and fumbled on the play.
