 Whilst opting to remain in Europe alongside Simmonds, Stewart signed to another lockout contract in the more competitive Czech Extraliga with HC Bílí Tygři Liberec on October 23, 2012.With the intention of playing alongside Simmonds and former NHLer Petr Nedvěd failing to materialize, and after five unfruitful games with Liberec, Stewart decided to return to Crimmitschau for the remainder of the lockout on November 13, 2012.Just under a month later, with new-found optimism of the lockout's end in sight and on advice to prevent injury, Stewart was released on his request from the remainder of his contract on December 7, 2012.
