=== Vikings' Robinson has fractured sternum ===
 
 Eden  Prairie,  MN (SportsNetwork.com)  -  Minnesota  Vikings cornerback  Josh
 Robinson  will  be out at  least 4-to-6 weeks  because of a fractured sternum,
 coach Leslie Frazier announced during Monday's press conference.
 
 Robinson  suffered the  injury in Sunday's 41-20 loss to the Seahawks. Frazier
 also  announced  that center  John Sullivan sustained  a concussion during the
 game.
 
 The  22-year-old Robinson has 58 tackles and four passes defensed in 10 starts
 this season. Xavier Rhodes will likely take Robinson's left cornerback spot in
 the  base defense,  and Marcus  Sherels would  be the  slot cornerback  in the
 nickel.
 
 Frazier  did not  say whether they would place Robinson on injured reserve yet
 with six weeks left in the season.
 
 Sullivan  will  have to  go through  the NFL's testing  protocol before he can
 return to action.
 
 Frazier  also  said that running  back Adrian Peterson,  who was hampered by a
 groin injury Sunday, would be evaluated this week.
 
 The Vikings play at Green Bay on Sunday.
