The Hamilton Tiger-Cats are leaving the door open for Chris Williams.

Ticats head coach and GM Kent Austin said the club would entertain Williams returning despite the disgruntled receiver's unsuccessful attempt to have the final year of his CFL contract voided.

An arbitrator ruled Tuesday that Williams' deal with the Ticats was binding even though it was negotiated by an unregistered agent, which is a violation of the CFL's collective bargaining agreement.

Williams, the CFL's top special-teams player last season, went to arbitration asking to be released from his deal with Hamilton reportedly so he could pursue NFL offers.

It remains unclear whether Williams will report to Hamilton or sit out the season, then pursue an NFL deal in 2014.

The other options Williams has are to rejoin the Ticats or ask to be dealt to another CFL team.
