The Week 12 matchup between the Pittsburgh Steelers and Baltimore Ravens is still up for grabs.

Dan Graziano of ESPN reports Monday's round of testing did not show any new positives on Baltimore's active roster. As such, the NFL is reportedly giving the Ravens the option to travel to Pittsburgh for Tuesday night's game:

However, ESPN's Adam Schefter also says the league is considering yet another postponement due to the complexity of the situation:

The latest postponement consideration might be due to the fact some Ravens players are expressing concern over playing.

ProFootballTalk reports a potential “strike” would be calamitous:

Per source, there are new fears of Ravens players refusing to play tomorrow night, which technically would be a wildcat strike. It could create major issues between NFL and NFLPA, if it happens. Potentially, it could jeopardize the balance of the season.

Even if the Ravens agree to play, a third postponement could have a pretty drastic impact on the schedule.

Baltimore was originally scheduled to play the Dallas Cowboys on Thursday, though that Week 13 matchup was moved to Monday in light of the second postponement. Meanwhile, the Steelers are slated to play the Washington Football Team on Sunday.

Those Week 13 games would inevitably have to be shuffled around in the event there is another postponement. Of course, if the Ravens are truly refusing to play, they will probably be pressured to forfeit the contest. That would be a hard sell, considering Baltimore (6-4) is fighting for its playoff life.

Regardless, Steelers-Ravens is a sticky situation, and it might get even messier.
