Jennings hasn't played professional baseball since August. He had a "minor knee injury" and ended up missing the rest of the season, and now apparently (according to rotoworld.com) hurt his back in March and was supposed to be out "4-6 weeks". Now he supposedly has a shoulder injury and has "no ETA". Is this guy made of glass? Is there anything else to the story? It seems odd to have "no ETA" unless it's a dramatically serious injury.
