SANTA CLARA, Calif. -- San Francisco 49ers cornerback Carlos Rogers remains optimistic about playing in Sunday's NFC wild-card game against the Green Bay Packers despite an injured right hamstring.

While Rogers didn't offer specifics about the results of an MRI exam done Monday, he said while leaving the practice facility Tuesday night that it was too soon to determine his status for the weekend.

This is the ninth-year veteran's first hamstring injury. He was hurt late in the fourth quarter of San Francisco's 23-20 win at Arizona on Sunday.

"We'll see, we don't know," Rogers said from his car. "It's all right. It ain't bad. We're taking it day by day."

The 32-year-old Rogers has 47 tackles, two interceptions and eight passes defensed for San Francisco (12-4), which takes a six-game winning streak into the playoffs. The 49ers seek their sixth championship after falling short, 34-31, to the Baltimore Ravens in last season's Super Bowl.

Coach Jim Harbaugh said he didn't yet know whether Rogers would play Sunday. Rogers has started all 16 games in each of his three seasons with the 49ers.

"We're always hopeful," Harbaugh said. "He's a little sore. These guys heal faster than the normal human being."

For his part, Rogers wasn't even close to ruling himself out in a rematch of last January's divisional-round game won 45-31 by the Niners.

"Oh, no," he said. "Hell no."

Rogers, who spent his first six seasons with the Washington Redskins, received a $31.3 million, four-year contract in March 2012. Yet with the emergence of Tramaine Brock and Eric Wright, Rogers' future with the franchise beyond this year is uncertain if he is unwilling to take a pay cut.

In November, Brock signed a $16 million, four-year contract extension that takes him through the 2017 season. The deal includes $7 million in guaranteed money.

If Rogers can't play against the Packers, Harbaugh has said Wright will assume a bigger role in his place -- playing the No. 3 cornerback spot as a key piece in the nickel defense.

"The NFL is all about the next guy in," Wright said. "I've played pretty much all the defensive back spots other than safety. So that's allowed me to grow mentally a lot faster, as well."
