The 49’ers have signed second-round draft pick Chico Rachal according to ProFootballTalk.com. Terms of the deal were not disclosed. Rachal, a guard from USC, comes in at about 6-foot-5, and 315 pounds. He has been working at tackle during the offseason with the Niners. His story is that he is coming into the league early to help his mother, who is battling a stomach tumor according to The Sporting News. He does have some injury concerns, but can be a force for the Niners on their line. Rachal becomes the third draft pick to agree to terms with the club.
