The Arizona Cardinals made a move on their practice squad on Monday. It was known they wanted to add a quarterback to have in case of an emergency. However, the team did not add the quarterback many thought they would.
Instead of adding Dennis Dixon, who joined the Cardinals briefly after Carson Palmer's shoulder nerve issue, they signed young quarterback Jeff Mathews, cutting linebacker Kion Wilson to make room for him.
Mathews (6-4, 229) entered the league with the Falcons in May as an undrafted rookie free agent out of Cornell. He spent training camp and preseason with Atlanta until he was released on August 24. He then signed with the Colts practice squad on August 31 and spent the first week of the season with Indianapolis until he was released on September 9.
While at Cornell, Mathews finished as the top passer in school history, setting 47 school records and 18 Ivy League marks while completing 901 of 1,447 passes (62.2%) for 11,284 yards and 72 touchdowns in 38 career games. As a senior in 2013, Mathews led the Ivy League in completions (228), attempts (360), passing yards (2,953), passing yards per game (328.1 avg.) and total offense per game (326.1 avg.) and was second in passing touchdowns (22).
My guess would be Arians talked to Indy's coaching staff. He still knows people over there and probably heard a good word or two.
