Fullback Michael Robinson became the sixth member of the 2011 team to reach an agreement to comeback in 2012. Robinson made the Pro Bowl last year, and the announcement of his return arrived late Thursday night via Twitter:

It's a two-year deal according to Brian McIntyre, who has the details here. That's from Mac's Football Blog, and if you don't go there regularly, you really should. It's a site that has a great deal of financial nitty gritty in the offseason, and provides great information on personnel during the year. You can also follow Brian on Twitter @Brian_McIntyre. Do it. You know you want to.
