Former Seahawks fullback Michael Robinson is scheduled to visit the Titans on Friday, according to a source. Robinson, signed as a free agent by the Seahawks in 2010, was due to make $2.5 million in 2013, before he was released. Robinson played from 2006-09 with the 49ers. He’s played in 103 career games. The Titans currently have fullback Quinn Johnson on the roster, but he missed practice on Thursday with a quad injury. Source: The Tennessean
