San Francisco 49ers' Jim Harbaugh: Vernon Davis is "a special creation"

San Francisco 49ers head coach Jim Harbaugh has hailed tight end Vernon Davis following his side's win over the St Louis Rams.

Davis caught two passes in the victory at Edward Jones Dome, including one for a touchdown despite carrying a hamstring injury.

"He's a special creation," Harbaugh told reporters. "He has different kind of blood flowing through him than you or I for sure."

The 49ers are 2-2 after week four of their season.
