Defensive end Anthony Spencer had successful surgery on his left knee today (Thursday), according to his agent Jordan Woy.
Spencer will be be sidelined about a month while recovering, likely keep him out the majority of the preseason. He should be ready for the start of the season.
The surgery was necessary after Spencer experienced discomfort in the knee during pre-camp conditioning tests on Saturday. It’s the same knee he hyper-extended during organized team activities in June. A magnetic resonance imaging exam confirmed a bone-bruise in Spencer’s left knee.
The Cowboys felt surgery was the best option and wanted to get this taken care of so it wouldn’t be a lingering issue during the season. Spencer will make $10.6 million after being designated as the team’s franchise player.
