Minnesota Vikings head coach Brad Childress announced that quarterback Brett Favre will start on Sunday against the San Francisco 49ers, Judd Zulgad of the Star Tribune.

"I think he's (Favre's) doing a good job of rounding into form," Childress said. "He has been throwing the football, there is no question about that. Just conditioning his legs.

"He's versed in our system and our calls."

Favre, who had an additional $3 million tacked onto his contract, is expected to play a series or two before giving way to Tarvaris Jackson.

Sunday's game will be broadcast nationally by NBC.
