The Minnesota Vikings officially completed a trade with the Houston Texans to acquire Sage Rosenfels by reaching a two-year contract extension with the quarterback on Friday.

According to a source, Rosenfels agreed to a two-year, $9 million extension with the Vikings, who gave up a fourth-round draft choice to acquire him. Rosenfels had one year remaining on his deal with the Texans that would have paid him $1.35 million.

He flew to Minnesota on Thursday and was scheduled to undergo a physical Friday morning.

Rosenfels is expected to compete with Tarvaris Jackson for the starting role in Minnesota. The Vikings have been trying to acquire Rosenfels for more than a year.
