Vikings interim coach Leslie Frazier confirmed Saturday that Joe Webb will make his first career start against the Bears on Monday night.
The rookie sixth-round draft pick from Alabama-Birmingham has completed two of five passes for eight yards in limited action. He also has one run for 16 yards.
The Vikings were expected to move Webb to receiver but moved him back to quarterback during training camp.
"He's fast. He's a big, athletic guy," Bears defensive coordinator Rod Marinelli said. "He's got a strong arm. You respect every man you line up against in this league and then we've got to go out and execute.
"This guy can move. He sees a crease and he'll take off. So we've got to make sure we're disciplined in our rush lanes and overlap, all the things we have to accomplish. It comes back to what we do. We know what he is; now we've got to go out and execute our plan."
