As we get closer to the first game of the 2015 NFL season, one prominent member of the Minnesota Vikings that spent much of the offseason battling injury issues is still up in the air for Monday night's opener.
John Sullivan, who has not practiced since 18 August because of back spasms, was again sitting out of practice on Monday. He was replaced at the center spot by Joe Berger, who played the position when Sullivan left last year's game against the Buffalo Bills.
The offensive line has already had plenty of issues this season for the Vikings.
