"The 49ers' victory came at a cost, as receiver Joshua Morgan sustained a fractured right ankle, a source close to Morgan told CSNBayArea.com on Sunday evening.

It is not known how long Morgan will be out of action. Morgan was the 49ers' leading receiver with five catches for 75 yards in the 49ers' 48-3 victory over the Tampa Bay Buccaneers at Candlestick Park.

Morgan was injured with more than four minutes remaining in the game when Tampa Bay cornerback Anthony Gaitor tackled him after a 19-yard reception from backup quarterback Colin Kaepernick to the 1-yard line with the 49ers leading 41-3."
