MINNEAPOLIS — Adrian Peterson will keep his uniform the same for the Minnesota Vikings — for now.

Don’t get rid of those purple No. 28 jerseys just yet.

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 cover all the unsold jerseys already produced with his current number.

That’s been NFL policy: Players interested in changing numbers must apply by March of the year in which they want to switch, and they have to buy the unused inventory to compensate the manufacturer.

Peterson said on Twitter the purported $1 million change fee “blew my mind” including five exclamation points at the end of that particular post.

Peterson said last week on Twitter he was pondering picking either No. 23 or No. 21, posting that No. 28 “has been good” to him but that he felt it was time for something new. Vikings cornerbacks Cedric Griffin and Asher Allen currently have No. 23 and No. 21, respectively, but players in all sports over the years have persuaded — financially or otherwise — teammates to trade them a coveted or customary number.

Peterson is rehabilitating from reconstructive surgery on his left knee after tearing the anterior cruciate ligament in late December. He needed 17 tweets — sometimes 140 characters just isn’t enough — to share his point of view on the number-switch policy and the origin of his No. 28. (He said he wanted No. 29 in high school in honor of Pro Football Hall of Fame running back Eric Dickerson, but his team didn’t have it. So he picked No. 28.)
