DETROIT -- Quick update following the Detroit Red Wings' practice Saturday at Joe Louis Arena:

--Pavel Datsyuk (bruised shoulder) said he is 50-50 for Sunday's game in Minnesota, but added that he thinks he will play. Asked if injury was from Drew Doughty hit last Sunday, he said, "No. It's too much celebrating.''

--Mikael Samuelsson will return to the lineup Sunday, after missing 12 games with a groin strain.

--Rookie Petr Mrazek will start in goal. He beat the Blues 5-1 on Feb. 7 in his NHL debut.

--Forward Gustav Nyquist was reassigned to the Grand Rapids Griffins.

--Johan Franzen had an ultrasound on his hip flexor, said it's strained. He has skated briefly before practice the past two days but won't play Sunday and said he doubts he'll be ready for Tuesday's game in Nashville.

--Forwards Darren Helm and Todd Bertuzzi, both out with back injuries, did not skate. Helm hasn't been on the ice in exactly three weeks. Bertuzzi is walking with a cane and is struggling. It's hard to imagine that he will be back anytime soon.

--Goaltender Jonas Gustavsson was assigned to Grand Rapids on a conditioning stint. He'll start Sunday for the Griffins. He's been out since Jan. 22.



--Coach Mike Babcock said he hadn't decided on his lines, but he used Valtteri Filppula with Henrik Zetterberg and Damien Brunner. He's not happy with Filppula's play and basically said he needs to get it together.
