Charles Cross's High-Ankle Sprain is a $104 Million Headache for the Seahawks

The Seattle Seahawks just handed left tackle Charles Cross a $104.4 million extension to be their blindside anchor, but human ankles do not care about nine-figure contracts.

According to Jordan Schultz, the 317-pound cornerstone suffered a high-ankle sprain during Sunday night's 20-3 win over the Kansas City Chiefs. Cross is officially week-to-week, which is NFL medical speak for a timeline that could mean anything from a fortnight to a month of nervous pacing on the sideline.

"Jordan Schultz reported Cross will be week-to-week moving forward as he recovers."

A high-ankle sprain for a normal person means you take the elevator instead of the stairs for a few weeks. A high-ankle sprain for a left tackle means trying to block 260-pound edge rushers while your pivot foot feels like it is made of wet cardboard.

Cross exited in the fourth quarter with Seattle comfortably leading 13-3, forcing backup Josh Jones into action. Jones has held his own filling in for Cross before, including a stretch late last season, but this is not exactly the ideal time for a depth test. The Seahawks are already trying to patch together offensive line continuity after dealing with a knee injury to guard Anthony Bradford.

This roster shuffle immediately shifts the math for anyone looking at the betting markets for next week. Seattle hosts the Chicago Bears on Monday Night Football, and Chicago is coming off a gritty 30-24 win over the New England Patriots. A backup left tackle in a primetime standalone game is the exact variable that makes oddsmakers adjust their totals and opposing defensive coordinators start drooling.

For now, the Seahawks have to survive the week and hope Jones can keep the pocket clean under the prime-time lights. If Cross is out for an extended stretch, Seattle's offense is going to have to get very creative, very fast, just to keep their quarterback upright.
