GREEN BAY, Wis. — Aaron Rodgers said he thinks he’ll be ready for the Green Bay Packers’ showdown Sunday with the Detroit Lions for the NFC North title.

Rodgers strained his left calf in last week’s win over Tampa Bay. He was already fighting an illness going into that game.

Coach Mike McCarthy hasn’t expressed high concern about Rodgers’ health. The strained calf did limit Rodgers’ mobility against Tampa Bay, though.

“I’m feeling good — except for the sickness and the calf thing,” Rodgers said with a laugh. “Other than that, I’m great, yeah.”

49ers

SMITH SAYS HE DIDN’T DRINK AT McDONALD’S HOME: San Francisco outside linebacker Aldon Smith acknowledged that he visited Ray McDonald’s home for a short time the day the ex-49ers defensive lineman is accused of sexually assaulting a woman.

Smith said he didn’t drink any alcohol and that he is regularly checked for sobriety. He served a nine-game suspension this year for violations of the NFL’s substance-abuse and personal-conduct policies.

Court documents unsealed Monday said the encounter occurred Dec. 14, a few hours after the 49ers returned from a 17-7 loss to the Seahawks in Seattle. The woman stayed with McDonald at his home the next day and drank vodka with McDonald and Smith, according to the papers. That’s when McDonald conceded that a sexual encounter occurred.

Cowboys

Fire guts McClain’s home: A witness reported seeing a car speeding away from the exclusive neighborhood where a suspicious fire gutted a mansion owned by Dallas Cowboys linebacker Rolando McClain.

Tuscaloosa (Ala.) County Sheriff’s Lt. Andy Norris said the vehicle could be a clue in the fire, which occurred Monday, but investigators had yet to determine whether the blaze was accidental or purposely set.

County detectives and investigators from the state fire marshal’s office were on the scene of the fire, which destroyed a six-bedroom, five-bath house listed for sale at $1.5 million.
