Rosenfels officially a Viking

Sage Rosenfels is officially a Minnesota Viking, Scout.com has confirmed, after the team traded to get him away from the Houston Texans.

The Minnesota Vikings and Houston Texans completed the rumored trade from earlier this week. QB Sage Rosenfels will go to the Vikings for a fourth-round pick, Scout.com has confirmed.

Rosenfels will sign a three-year, $9 million deal with Minnesota and the trade is expected to be announced later on Friday. Rosenfels will compete against Tarvaris Jackson for the starting quarterback job.

The Houston Chronicle reported the deal was in the works earlier this week. Sports Radio 610 in Houston reported the contract offer from Vikings earlier this week.

Minnesota now has four quarterbacks under contract. Veteran Gus Frerotte is on the final season of his two-year deal and probably is the odd-man out. Frerotte has a cap number of $2 million which includes a $250,000 roster bonus, a league source said. As of Thursday, Minnesota was projected to be more than $30 million under the salary cap once their cap credits were added.
