The Pittsburgh Steelers have signed tackle Kyle Jolly to the 90 man roster according to several online reports. Jolly was released by the Atlanta Falcons earlier this month after spending time on their practice squad in 2011. Jolly was with the Steelers last year at training camp, but released prior to the start of the season and had spent time on their practice squad over the course of the last two seasons. No word of who was released to make room for Jolly.
Matt Katula also reportedly worked out for the Steelers. He played with the Baltimore Ravens from 2005 to 2009 and has spent time the last two seasons on the rosters of the New England Patriots and the Minnesota Vikings.
ETA: Reportedly it was the Oakland Raiders and not the Steelers that worked out Ikaika Alama-Francis and Tory Humphrey.
