The Lightning's telling trip just got tougher.

Wing Ondrej Palat flew back to Tampa for more tests Monday and will be out indefinitely, a big blow to the Lightning's shutdown line. Palat suffered a lower-body injury getting speared by Minnesota's Jared Spurgeon in the third period of Saturday's loss.

The Lightning recalled centers Matthew Peca and Michael Bournival from AHL Syracuse, the two expected to join the team for Monday's game against the Blackhawks.
