Veteran cornerback Chris Carr was by far the biggest surprise cut as the Vikings trimmed their active roster of 21 players to reach the 53-man roster by the 8 p.m. deadline. Also cut was 12-year veteran Sage Rosenfels, the No. 3 QB who was given a $500,000 guarantee for 2012 as part of a two-year deal he signed after last season.

Here's how the Vikings reached the 53-man limit:

Placed On Reserve/Injured: OT DeMarcus Love.

Vested veterans waived: CB Chris Carr, DE Jeff Charleston, S Eric Frampton, QB Sage Rosenfels.

Waived: WR Manny Arceneaux, DT Chase Baker, OG Chris DeGeare, FB Ryan D’Imperio, CB Bobby Felder, DT Trevor Guyton, RB Lex Hilliard, OG Tyler Holmes, CB Reggie Jones, OT Kevin Murphy, LB Corey Paredes, OG Austin Pasztor, DE Nick Reed, C Quentin Saulsberry, TE Mickey Shuler, RB Jordan Todman.

The Vikings only had to clear 21 players because they get a roster exemption for receiver Jerome Simpson, who will serve a three-game suspension to start the season.

Carr came to the Vikings from Baltimore and was working with the No. 1 nickel defense consistently through training camp and the preseason. There was speculation that he might eventually be elevated to a starting role so that 35-year-old Antoine Winfield could play only in the nickel.

Instead, the Vikings decided to keep these six corners: Winfield, Brandon Burton, Marcus Sherels, Chris Cook, Josh Robinson and Zack Bowman. Sherels' case was helped tremendously by his status as the No. 1 punt returner and Percy Harvin's primary backup at kickoff returner.

Rosenfels' release was surprising only because he was considered a security blanket for new general manager Rick Spielman. But the rocket right arm and the greater upside for 24-year-old McLeod Bethel-Thompson trumped the comfort of having the 33-year-old Rosenfels around to help the younger Christian Ponder and Joe Webb.

The Vikings will assemble their practice squad on Saturday morning. Their final 53-man roster could change tomorrow evening based on whether they're awarded any players they put in claims for. The Vikings are third in line for waiver claims, so they have a much better chance of getting players they put in claims for. 

Youth movement continues

Of the 53 players the Vikings currently have on their active roster after Friday’s cuts, eight are rookies with 16 more entering either their second or third seasons in the NFL. Defensive tackle Trevor Guyton was the only player from this year’s 10-man draft class to be waived. Guyton, however, seems to be a prime candidate to be added to the practice squad.

Of the 10 players the Vikings drafted in 2011, nine are still around. The only one missing is Ross Homan, a sixth-round pick who was cut before last season.

Love goes on I.R.

The Vikings placed second-year offensive tackle DeMarcus Love on injured reserve Friday, expecting him to need surgery on a lingering shoulder/pectoral injury. As a rookie last season, Love was inactive for all 16 games. He was expected to supply some depth at left tackle behind Matt Kalil, though starting left guard Charlie Johnson would also be an emergency option there. The only other back-up tackle on the roster right now is Pat Brown.
