Will Ray's Badly Thrown Grenade Come Back to Haunt Him on 'SEAL Team'?

Ray's shoulder injury came up again on SEAL Team, after weeks of questioning if the storyline had been dropped. As Ray threw a grenade to take out the sniper, he failed to throw it far enough and it hit the side of a building. We never saw if anyone was around when the grenade exploded, but it looks like this badly thrown grenade could come back to haunt him.
