With 90 players on NFL rosters for a majority of the preseason, most teams had two guys wearing the same jersey number. The San Francisco 49ers doubled up on a few numbers as well.

Both cornerback Kenneth Acker and running back Mike Davis rocked No. 20. First-round pick Arik Armstead and offensive lineman Jordan Devey shared No. 69 while Jarryd Hayne and Jermaine Whitehead both wore No. 38.

Those duplicates are no more now that the roster has been whittled down to 53 players and 10 more being added to the practice squad. Of note, Armstead moved to No. 91, Davis took No. 22 and Hayne kept No. 38.

Here's the full list of changes:

DL Armstead - 91

RB Davis - 22

OL Devey - 65

DL Glenn Dorsey - 90

C Nick Easton - 69

LB Shayne Skov - 56

RB Gaskins - 30 (Practice Squad)

OT Tanner Hawkinson - 76 (Practice Squad)

DL Garrison Smith - 78 (Practice Squad)

S Whitehead - 33 (Practice Squad)

WR Dres Anderson - 17 (Injured Reserve)

Notes:

Dorsey wore No. 91 in training camp but is back to the number he sported during his first two years with the 49ers ... Davis wore No. 28 in college, but that number is currently occupied by starting running back Pierre Garçon ... Armstead added a one to his college number, 9 ... Gaskins wore No. 40 during the preseason ... Anderson was No. 6 ... Skov shared No. 48 with rookie tight end Busta Anderson. Now Busta has the number to himself ... Smith, or "G-Baby" as the team calls him, rocked No. 65 in training camp and the preseason.

A few of the players took to social media to celebrate their new digits.
