They’ve found one in Josh Portis.
The team originally signed Portis as an undrafted rookie out of California (Pa.) University in 2011. Portis was on the active roster that year, and he was relegated to the practice squad for most of 2012. Eventually, he was cut from the practice squad.
Portis is now the second quarterback on the roster. The team presumably will add one or two more before the launch of Organized Team Activities and, later in the year, training camp. Names that have been mentioned as possible additions include Matt Leinart and Vince Young.
