We have signed QB Logan Thomas off the practice squad.
To make room on the roster for Thomas, we waived G/T Jeff Linkenbach.

Ian Rapoport reports that the decision to promote Thomas was to prevent the Bengals from signing him to their active roster.
Thomas, 24, still has another three years remaining on his four-year, $2,652,092 rookie contract, which includes base salaries of $510,000 (2015), $600,000 (2016), and $690,000 (2017).
Miami wound up claiming him off of waivers after he was deemed expendable by the Cardinals after they traded for Matt Barkley. However, he was waive at the start of the season, but was added to their practice squad just a few days later.
Last year, Thomas appeared in two games for the Cardinals, even though they lost Carson Palmer and Stanton for the season. He threw for 81 yards and a touchdown, but completed just a single pass attempt.
