Quarterback - Philip Nelson suffered a hip pointer in the midst of his career day against a lackluster Indiana defense. After arguably his best game (the only contender would be last year's game against Indiana's other B1G team, Purdue), Nelson is listed as the starter despite the hip pointer. While this is the first time in B1G play that Nelson has been listed alone at starting QB, expect backup Mitch Leidner to get some playing time as well.
Running Back - Rodrick Williams Jr is also not listed on this week's injury report after missing three straight games with Turf Toe. Getting Rodrick back would be a huge boost to depth at running back although David Cobb has proved himself capable of being the bell cow there as he is closing in on being the Gophers first 1,000 yard rusher in a few years.
Wide Receiver - Derrick Engel was also injured late in the Indiana game but like Nelson he's not listed on the injury report. Whether or not Engel's ankle injury slows him down remains to be seen but he's coming off a game in which he averaged 24.3 yards per catch on four catches for 97 yards and 2 touchdowns. Engel has five touchdowns on the year, four of which have come during the Gopher's current three game Big Ten winning streak. While Donovahn Jones appears to be emerging at WR and TE Maxx Williams has been a consistent weapon though the air, the Gopher's have struggled through the air and Engel's re-emergence has been a large part of Nelson and the passing games improved numbers recently.
Center - Starter Jon Christenson is out for the year with an apparent broken leg suffered in the Indiana game. While he was able to leave the hospital wednesday following surgery to begin the healing process, it seems unlikely that Christenson will return to the field before next summer. Tommy Olson stepped in at Center and performed well. Whether Tommy remains the starter at center the rest of the way remains to be seen. Last year the Gophers used multiple lineman at center due to injuries. One of those lineman used was current guard Zac Epping. It's not out of the question that Epping slides over to center and Olson or one of the plethora of talented but unproven backups steps in at guard.
