The Dolphins don't intend to release quarterback Sage Rosenfels from injured reserve at this point, according to sources. Reports indicated that Miami would release Rosenfels, who then would join the Texans, but the Dolphins plan to hold on to the veteran quarterback at this time, despite the undisclosed illness that landed him on IR. The Texans are in the market for a quarterback after Matt Leinart was knocked out of Sunday's game against the Jaguars with a collarbone injury. The Texans already lost Matt Schaub for the season to a right foot injury.
