DALLAS (AP) _ Dallas Stars center Joe Nieuwendyk was helped to the locker room after being hit in the leg by Edmonton Oilers defenseman Scott Ferguson late in the first period of Saturday's playoff game.

Nieuwendyk had just given up the puck when Ferguson skated into him from across the ice. Nieuwendyk immediately clutched his right leg near his knee as he fell to the ice. He remained down for several minutes.

The Stars later said he suffered a leg injury and his return was questionable.

Typical pushing and shoving followed the hit, then another round of blows began when Ferguson was spotted standing alone near his bench, smirking.

Edmonton's Daniel Cleary came out of the pile with a cut on the side of his nose and Dallas' John MacLean was sent to the locker room.

Cleary and teammate Ryan Smyth were both penalized for roughing, as were MacLean and teammate Derian Hatcher. Ferguson was not penalized for the blow that started it all.

The first period was filled with rough stuff, leading to 12 penalties.

Nieuwendyk had scored on a power play midway through the period, giving Dallas a 2-1 lead. The game was tied at 2 at the time of the fracas and Edmonton led 3-2 at the end of the first.
