MARQUETTE - Northern Michigan University senior running back Casey Cotta was carted off the practice field on Thursday morning with a left leg injury.
The severity of the injury is not known at this time.
The injury occurred toward the end of the first of two schedule practices Thursday. It was the second full-padded practice of the season and sixth overall since training camp began Saturday.
Cotta injured himself after scoring a touchdown with the first-team offense on a third and short situation, powering just over 10 yards to cap the drive during team 11-on-11 drills. He didn't get up after the score, however, and was attended to by the team's athletic training staff and Dr. John Lehtinen.
Cotta missed the first half of the 2012 season with a hamstring injury, but appeared in the final five games to finish third on the team in rushing with 398 yards on 73 carries. He averaged 79.6 yards per game and 5.5 yards per carry in the 'Cats three wins and two losses, plus he scored four touchdowns.
Cotta transferred to NMU in the spring of 2010 after playing two seasons for Modesto Junior College in California. He was a member of the scout team in the fall of 2010, but missed all of 2011 after suffering a torn ACL four days into camp.
Cotta, junior Wyatt Jurasin and redshirt freshman Keon Collier were part of a three-man rotation at running back that was expected to anchor the backfield this season.
Jurasin and Collier are both coming off season-ending injuries from the 2012 season.
