New York Giants quarterback Drew Lock will have an MRI on his right shoulder after injuring it in Sunday's 34-7 loss to the Atlanta Falcons, head coach Brian Daboll told reporters Monday. The results of Monday's MRI will help the team decide which quarterback gets the start in Week 17's matchup with the Indianapolis Colts, Daboll said, continuing a season trend of question marks at the position. New York has used four different quarterbacks this season, as longtime starter Daniel Jones was benched and later released on Nov. 22. Lock sat out the Giants' 35-14 loss in Week 15 to the visiting Baltimore Ravens due to heel and left elbow injuries.
