The NFL fined Vikings safety Harrison Smith $10,026 for his flagged hit that injured Bears quarterback Mitchell Trubisky, a league source told the Star Tribune, during the Vikings' 25-20 loss in Chicago last Sunday night.

Smith was penalized for unnecessary roughness on the hit at the end of Trubisky's 5-yard run in the fourth quarter. It was the only fine from four personal fouls in the game, including a late hit by linebacker Eric Kendricks and a roughing the passer by Bears defensive tackle Akiem Hicks.

"Harrison has got to pull off the quarterback," Vikings head coach Mike Zimmer said Monday.

Smith's defense of the play was that Trubisky was the ball carrier on a designed run.

Because of the hit, Trubisky was sidelined for the Bears' 23-16 win against the Lions on Thanksgiving. Bears head coach Matt Nagy has told Chicago reporters that he'll require a short recovery.
