Favre, 40, who has consistently said throughout the offseason that he was unsure if he'd play this season, is expected to make a public statement later today, the paper said.

FAVRE WATCH: What Favre has said about a potential return since January
Favre had surgery on his left ankle in May, and he told USA TODAY last month that he just couldn't decide if his body would hold up to the stress of a 20th NFL season.
But Favre has been through this before. In 2008, he retired from the Green Bay Packers in March only to return in July and be traded to the New York Jets.
He then retired in early 2009, only to make a comeback for last season. He initially told the Vikings in late July 2009 that he would remain retired, but changed his mind by mid-August.
Vikings coach Brad Childress has said he's content to wait as long as possible for Favre, and believes he only needs 2-3 weeks of preparation for the season.
