The Los Angeles Kings dropped a big game in Alberta on Monday, falling to the Edmonton Oilers 4-2.

It was a game the Kings led twice in, but Edmonton clawed back in both times and capitalized on a weak third period from LA to grab a win.

The turning point of this game came midway through the second period after the Kings failed to convert on a 5-on-3 powerplay. 

Stuart Skinner came up with a few huge saves, particularly on Adrian Kempe and Anze Kopitar, which swung all the momentum in Edmonton's favor.

The Oilers then scored on a power play of their own, which tied the game at two, and the Kings never really got back into the game.

A sloppy third period where they were out-chanced and outshot for the majority of the frame was the nail in the coffin for another subpar Kings effort.

Despite grabbing a win against Anaheim on Saturday, this is three mediocre games from this team.

We aren't at a stage where alarm bells need to be ringing, this team is still 6-3-0 since the All-Star break, but this looks a bit like the pre-All-Star break Kings over the last few games.

Not playing terribly, but not playing well enough to earn wins either.

Where there should be plenty of concern is in the health of Adrian Kempe.

Kempe fell awkwardly towards the end of the game and immediately skated off holding his left arm/wrist. After a quick look from the trainer, he then immediately left for the lock room in clear discomfort. 

Head coach Jim Hiller did not have an update on Kempe after the game but did make this comment.

"For him not to finish the game, something's not right."

Not an encouraging observation from Hiller.

Losing Kempe, who currently leads the team by four points, would be devastating. Any team who loses their leading scorer would take a hit, but a team struggling for offense like the Kings might not recover.

They're already down two key players in Mikey Anderson and Viktor Arvidsson and adding a third impact player would be catastrophic. 

If the injury is long, or even medium-term, it's hard to see this Kings team making a strong push down the stretch here.

They'd be relying heavily on Kopitar, Trevor Moore, Quinton Byfield and Pierre-Luc Dubois to carry the load offensively. They'd also need someone like Arthur Kaliyev to step up.

While I'm sure some of those players would rise to the challenge, expecting it from all of them is probably unrealistic. 

Not to mention the issues they're having on the back end right now. Lost in the mix of Kempe's injury was the Kings' top pair of Vladislav Gavrikov and Drew Doughty finishing Monday's game a -3.

This means they were on the ice for all three Oiler's even-strength goals. 

In the few games they played together last season when Anderson was hurt, Gavrikov and Doughty were poor together and that seems to be carrying over now.

A serious injury to Kempe might be one blow too many for this team and might lead to a change of plans come the trade deadline.
