Cardinals receiver Anquan Boldin has a hamstring injury.
The seven-year veteran strained his hamstring in Tuesday's practice. He was held out of practice today.
Cardinals head coach Ken Whisenhunt has not ruled him out of Friday's preseason game with the Green Bay Packers at University of Phoenix Stadium.
He said the Cardinals would watch Boldin's injury closely and make a determination later this week.
The Cardinals' receiving core has suffered two minor injuries over the preseason. Arizona receiver Steve Breaston, in the Cardinals' preseason opener against the Pittsburgh Steelers, suffered a bruised knee and sprained PCL. The injury--like Boldin's--is not believed to be serious.
Boldin was Arizona's second-leading receiver last season, hauling in 89 passes for 1,038 yards and 11 touchdowns. Breaston caught 77 passes for 1,006 yards and three touchdowns.
Boldin suffered a hamstring injury late last season, forcing him to miss the division round playoff game, a 33-13 win over the Carolina Panthers.
