The Tampa Bay Buccaneers announced on Monday they have signed safety Troy Nolan, an unrestricted free agent who has spent most of his NFL career with the Houston Texans, on Monday as they began the second week of their 2013 training camp. To make room for Nolan on the 90-man roster, the Buccaneers waived guard Jeff Olson, who had joined the team on Saturday. Nolan entered the league as a seventh-round draft pick of the Texans out of Arizona State in 2009, but he landed on injured reserve as a rookie due to a wrist injury. When he finally made his NFL regular-season debut in 2010, he did so in style, helping Houston beat the Oakland Raiders, 31-24, by intercepting two passes, including one that ended the Raiders' last possession with less than two minutes to play.
