He was hurt during the second quarter and a subsequent X-ray revealed the extent of the injury.
Team doctors did not announce anything concerning his playing status. The former fourth-round pick by the Packers in 1999 was injured on a three-yard scramble. He finished 7-of-13 passing for 44 yards in his first action of the pre-season, and did not lead the team to any points.
"I felt pretty good, but obviously I'm not where I want to be, as I aggravated my injury," Brooks told the New Orleans Times-Picayune.
His passer rating for the contest was only 61.1.
