Carson Wentz has been placed on injured reserve and will undergo season-ending shoulder surgery, according to CBS Sports NFL insider Jonathan Jones . Wentz made five starts this season for the Vikings in relief of starting quarterback J.J. McCarthy , who is expected to return to the lineup for this week's game against the Detroit Lions .

Along with McCarthy, the Vikings' quarterback room consists of Max Brosmer , an undrafted rookie who will now move up to the No. 2 spot on the depth chart. Brosmer, who started for the Minnesota Gophers last season, has made three relief appearances this season, going 5 of 8 passing for 42 yards.

Wentz played with considerable pain in his left (non-throwing) shoulder for more than half of his five starts, according to the Vikings' website .
