Disaster for Travis Green and the Ottawa Senators

An upper-body injury is the frustrating culprit. This massive news drops like an anvil at the absolute worst possible time for the franchise.

The Eastern Conference playoff race is an absolute dogfight right now. Every single point matters down the brutal stretch run.

Through 62 games, the Senators are battling extremely hard to stay in the postseason mix. They currently sit at 71 points with a respectable 31-22-9 record.

They are right in the thick of the hunt, sitting firmly in the middle of the pack. But the margin for error in this league is always razor thin.

Losing your premier guy on the blue line completely changes the dynamic of the locker room. The entire defensive game plan must shift immediately.

You simply do not replace a 23-year-old workhorse of this caliber with internal minor-league call-ups or depth pieces.

Sanderson was putting together a truly dominant campaign before this crushing upper-body setback derailed his momentum.

He had already racked up 48 points this year. He found the back of the net 11 times over those 62 games, showing off his heavy shot.

Add in his 37 assists from the back end, and it becomes obvious. He is the main engine driving the transition game every single night.

He is not just an offensive threat, either. He boasts a stellar +9 rating while eating massive top-pairing minutes against the toughest lines in hockey.

Over his NHL career, he has matured into a legitimate two-way force. Reaching 175 points in 298 career games proves his elite consistency at this level.

Both the penalty kill and the power play will suffer immensely without his incredible ice vision and crisp passing.

Now, the rest of the defensive group has to step up and absorb those grueling shifts. The pressure on the remaining veteran defensemen is massive.

Every remaining game on the schedule just became significantly more difficult. It is absolute gut-check time in the nation's capital. They must survive without their anchor, or watch their playoff dreams fade entirely.
