San Francisco's Trent Williams (elbow) out for Week 17's contest against Seahawks

San Francisco 49ers offensive tackle Trent Williams (elbow) is ruled out for Week 17's game against the Seattle Seahawks.

What It Means:

According to head coach Kyle Shanahan, Williams will miss Week 17's season finale after suffering an elbow sprain. Without Pro Football Focus' top ranked offensive tackle, San Francisco's rushing attack could see a dip in production after Williams produced a league best 86.7 run block rating.

Expect Justin Skule to fill in at left tackle on Sunday. In 108 pass snaps this season, Skule has allowed one sack, four quarterback hits, and 12 total pressures.
