The Green Bay Packers won't have injured wide receiver Greg Jennings available for Sunday's game against the Indianapolis Colts. Jennings' groin injured flared up during the first half of the Packers' win last Sunday over New Orleans and the team said Thursday that he would sit out this week. Jennings didn't return for the second half against the Saints and didn't practice Thursday, according to NFL.com. The Packers indicated that they want to proceed with caution rather than risk further injury. "I had a conversation with Greg before practice and we just talked through the history of his injury and we felt like we're going around in a circle," Packers coach Mike McCarthy said. "So we just felt, 'Why take this decision all the way to Sunday?'" Jennings caught his first touchdown pass of the season on Sunday against the Saints and has seven receptions in three games.
