Jennifer Hammond of WJBK provided a shot of the ambulance but noted that he was at least conscious as he was taken away:

Martin punted the ball four times in a 34-22 loss. He also serves as the team's kickoff specialist and had one successful onside kick during the team's comeback attempt.
The 28-year-old is in his sixth season with the Lions and came into the day averaging 45.4 yards per punt (12th in the league). Martin missed six games last season because of an off-field incident, but he has played every other game in his career.
