Titans quarterback Marcus Mariota is dealing with a pinched nerve in his elbow and hasn't fully regained feeling in his hand. Despite this he is still expected to try to play on Sunday.
As a QB not having feeling in your hand seems like a pretty big deal. Have no worries Titans fans, if he's unable to go Blaine Gabbert will be ready to step in.
There is no word on how long it will take Mariota to fully recover, but the fact that the Titans are willing to put him out there lets us know exactly what they feel about the current backup quarterback position.
