(WNFL) - The Green Bay Packers practiced with only four healthy corners yesterday, as they get ready to host Minnesota on Sunday. Rookie Micah Hyde sat out with a groin problem, but he expects to be back on the field today. Sam Shields and Casey Hayward continued to sit out with hamstring injuries, and James Nixon missed practice with a bad knee. Practice squad corner Jumal Rolle took a lot of snaps, but he has not been called up to the 53-man roster. None of the Packers' other injured players returned to the field yesterday. Meanwhile, linebacker Clay Matthews tells E-S-P-N that a 15-thousand-dollar fine for his out-of-bounds hit on San Francisco quarterback Colin Kaepernick in Week-One was cut in half after he appealed it. Matthews also said the league withdrew a 15-thousand-750-dollar fine for roughing the passer in the loss to Philadelphia two weeks ago.
