Arizona waived Blankenship (undisclosed) with an injury settlement Wednesday.
Blankenship filled in for Matt Prater during Week 7 and made both of his field-goal attempts, including a 50-yarder, but he missed one of his three extra-point tries. Prater returned in Week 8 but wasn't cleared for kickoff duties, so Blankenship handled that role. However, Blankenship appears to have suffered an injury of his own during the contest and was waived with an injury settlement Wednesday. Once healthy, Blankenship will be allowed to sign with a new team.
