The Houston Texans have traded for Ryan Mallett from the New England Patriots, sending a conditional sixth or seventh round pick in 2015.

The Texans are entering the 2014 season with Ryan Fitzpatrick as their starter.

To make room for Mallett on their roster, the Texans will waive quarterback Case Keenum, a source told ESPN.

Mallett was passed on the Patriots' depth chart this summer by rookie Jimmy Garoppolo, a second-round pick who impressed throughout training camp and the preseason.
