The Las Vegas Raiders are still reeling after their last-second blocked field goal loss to the Chicago Bears in Week 4. But now, Las Vegas' pain has gotten even sharper.

Alongside his high-ankle sprain, Miller also has a hairline fracture, via Ian Rapoport of the NFL Network. He is set to be placed on injured reserve, meaning he will be missed to miss at least the next four games.

It wouldn't be shocking to see Miller out for longer though. The injury update is worst possible scenario for the Raiders. Pete Carroll is still trying to break in his new offense with quarterback Geno Smith at the helm. But now he'll have to do so without his best offensive lineman.

Before going down with injury, Miller ranked third out of 108 tackles with his 85.5 grade from Pro Football Focus. He excelled in pass blocking, ranking third with his 87.9 mark. Furthermore, that success isn't anything new for Miller, who ranked 14th out of 140 tackles with a 80.6 grade.

That success is exactly why the Raiders gave Miller a $66 million contract extension during the offseason. But his absence will now be a massive gut punch to Smith and the offense. Smith has already been sacked 12 times on the year, tied for 12th-most in the league.

Already 1-3 on the season, the Raiders are looking for a major comeback. Especially with how things went down in Week 4. However, that is going to be all the more difficult without Miller on the field. They'll monitor him closely over the next four weeks and hope his injuries aren't season ending.

On first look though, things don't seem optimistic.
