On December 15, 2006, Henderson agreed to a five-year contract extension with the Vikings. The deal was reportedly worth over $25 million with $10 million guaranteed. In April 2008, the Vikings signed Henderson's younger brother,
Erin, as an
undrafted free agent out of Maryland. Henderson was placed on season-ending
injured reserve after he dislocated multiple toes on October 6, 2008, in a game against the
Tennessee Titans. In Week 13 of the 2009 season, Henderson suffered a broken left femur during a game against the
Arizona Cardinals. The injury occurred when his leg twisted violently as he was trying to tackle
Tim Hightower and hit
Jamarca Sanford's helmet. He was removed from the field on a motorized cart, accompanied by his younger brother and teammate Erin. Henderson stayed overnight in Phoenix for surgery, and missed the rest of the season. He made a full recovery in time for 2010 training camp. After what was described as a "remarkable recovery", Henderson was selected for the
2011 Pro Bowl.
