AP reports San Francisco 49ers TE Eric Johnson will miss at least the next two weeks after injuring his left knee during practice. Johnson, who has 32 catches for 282 yards and two touchdowns this season, missed two of the last three seasons with serious injuries. He had a team-leading 82 catches for 825 yards in 2004. Johnson will be replaced by rookie TE VernonDavis, the sixth overall pick who missed seven weeks with a broken leg. Davis, who has just six catches, returned to the starting lineup last week against St. Louis.
