GREEN BAY (AP) -- Coach Mike McCarthy plans to leave everyone guessing what the offensive line will look like when the Packers face the Minnesota Vikings on Sunday.
   "I have some options," McCarthy said Friday.
   McCarthy is feeling good about what he has available with the injury-riddled line as the Packers welcome back former quarterback Brett Favre to Lambeau Field for the first time.
   Veteran tackles Chad Clifton and Mark Tauscher were full participants in practice Friday.
   Clifton, who missed three of the last four games with an ankle injury, is questionable for Sunday. Tauscher, who hasn't played since re-signing with the Packers on Oct. 12, is probable.
   McCarthy said decisions about who will start against the Vikings won't be made until after he meets with his coaching staff Saturday.
   Rookie T.J. Lang and first-year starter Allen Barbre are the other candidates to start at left tackle and right tackle, respectively. They both played in last Sunday's 31-3 win at Cleveland.
   McCarthy reiterated that Barbre remains the starter at right tackle, even though the Packers brought back Tauscher amid a rash of sacks to quarterback Aaron Rodgers. Tauscher was Green Bay's starting right tackle from his rookie season in 2000 until he suffered a serious knee injury late last season.
   "We've got to make sure Mark's ready to play, and Allen Barbre needs to continue to improve and keep his job," McCarthy said.
   Who makes the start at left tackle Sunday is more of a mystery, but Lang is preparing as though he'll make his second straight start.
   That would mean another shot against Minnesota defensive end Jared Allen, who had 41/2 of the eight sacks on Rodgers in the teams' first meeting Oct. 5 -- a 30-23 Vikings win.
   "If I happen to play Sunday, then I'm going to take advantage of the opportunity," Lang said. "I'm going to go against one of the best pass rushers in the league."
   Lang finished the earlier game lined up opposite Allen after Daryn Colledge, who had started in Clifton's absence, left with a knee injury early in the fourth quarter.
   Rodgers, who has a sprained foot, went through the full practice Friday after being limited the previous two days and is probable for Sunday.
