OWINGS MILLS, Md. -- Left tackle Eugene Monroe is scheduled to undergo a magnetic resonance imaging test on his shoulder Wednesday, which could add some clarity to one of the more uncertain positions on the Baltimore Ravens this season.

"Between him, his doctor and his agent, he’ll have to make a decision about whether he wants to play with it for the rest of the year," Baltimore Ravens coach John Harbaugh said.

It will be Monroe's decision on whether he wants to play this year. It will be the Ravens' decision on whether he plays in Baltimore next season.

Monroe's future will be one of the biggest questions for the Ravens this offseason. Do the Ravens want to risk paying Monroe $6.5 million in 2016 for missing more games? Or will Baltimore part ways with Monroe and take on $6.6 million in dead money?

Monroe is worth being the 12th-highest paid left tackle in 2016 if he can stay on the field. Pro Football Focus has rated him the 16th-best left tackle this season.

There's just no guarantee anymore that Monroe will play. In fact, there's a better chance that he's on the sideline.

Here's a look at Monroe's lack of durability:

Has missed 12 of 30 games (including playoffs) since signing his five-year, $37.5 million deal before the 2014 season

Has started and finished three of his last 16 games (including playoffs) dating back to Week 16 of last season

Has been sidelined for as many games (six) as he started this season

Has participated in 304 snaps this season, which represents 37.7 percent of the Ravens' plays

Has missed time due to four injuries since the start of the 2014 season: Knee (four games), ankle (three), concussion (three) and shoulder (two)

Monroe's injuries have repeatedly pressed James Hurst into a significant role. Hurst has taken heat for committing a costly holding penalty in Sunday's 15-13 loss to the Miami Dolphins and for getting pushed into Joe Flacco a couple of weeks ago that led to the quarterback's season-ending knee injury.

But Monroe has to share in the blame, too. If he was more durable, the Ravens would have their high-priced investment at left tackle instead of an undrafted lineman.

Harbaugh didn't mince words when addressing how the Baltimore Ravens have had to juggle the left tackle position because of Monroe's inability to stay healthy.

"It has been a real challenge," Harbaugh said.

Can the Ravens afford to put faith in Monroe for 2016? Or is it time to find someone in the draft or free agency to protect Flacco's blind side next season?
