Glen Coffee retires Posted by Mike Florio on August 13, 2010 2:41 PM ET Well, we now have an explanation for Glen Coffee's mysterious absence from training camp. According to Matt Maiocco of CSNBayArea.com, Coffee has retired. Per Maiocco, Coffee exits the game after drawing the ire of position coach Tom Rathman by getting blown up by Mike Balogun on a blitz. A third-round pick in 2009 out of Alabama, Coffee had 83 carries for 226 yards in 14 appearances as a rookie, with two starts. The 49ers are left with Frank Gore, Michael Robinson, and Anthony Dixon at running back. We've got a feeling that they'll be making a move to replace Coffee, soon. The team will be able to recover the balance of his $828,000 signing bonus on a four-year deal. It works out to $621,000.
