Demetrius Knox has been bitten by the injury bug again.

The former Ohio State guard was carted off the field late in the Seattle Seahawks' preseason game against the Minnesota Vikings on Sunday night. Seahawks coach Pete Carroll said after the game that Knox suffered a quadriceps muscle injury.

Unfortunately for Knox, it's the second time in less than a year that he's suffered an injury that required him to be carted off the field. During the final minutes of Ohio State's game against Michigan last season, Knox suffered a Lisfranc foot injury that knocked him out of the Buckeyes' final two games of the year, bringing his Ohio State career to an end.

After recovering from the injury all offseason, Knox was only cleared to return to training camp for the Seahawks just a few weeks ago. Signed by the Seahawks as an undrafted free agent, Knox was attempting to earn a spot on the team's 53-man roster, but now, it appears more likely that he will spend his rookie season in the NFL on injured reserve.
