Lock is questionable to return to Monday's preseason game against the 49ers due to a hand injury, Mike Klis of 9News Denver reports.
Lock suffered the injury early in the third quarter when he appeared to fall on his left hand while scrambling to avoid pressure. The severity of the rookie second-rounder's injury remains unknown at this time, but the signal-caller reportedly could continue taking snaps into the fourth quarter if he's cleared to return.
