Adrian Peterson will still wear No. 28 for the Minnesota Vikings - for now.
The star running back said in a series of posts on his Twitter page on Wednesday that he balked at switching because he was told he would have to pay $1 million to buy out the unused inventory of the jerseys already produced with his current number.
The NFL says a player must apply to change his number by March of the year in which he wants to switch. The league is changing jersey manufacturers from Reebok to Nike this year. NFL spokesman Brian McCarthy says the number-switch policy hasn't yet been finalized for 2012.
Peterson said last week on Twitter he was pondering picking either No. 23 or No. 21.
