Joe Webb started a playoff game for the Minnesota Vikings last season in an emergency situation, but he will move full time to wide receiver this season.
"We had been talking about it for a while, and we made the decision that this was the way to go after we had our draft," Leslie Frazier said.
Webb was drafted as a wide receiver in 2010.
"It's going to be very interesting," Webb said about the position switch. "I haven't played it since my rookie minicamp, but I think I can adjust to it pretty good. You just have to put in a lot of work. (Wide receivers) coach Stew (George Stewart) will do a lot of that with me, so we'll see what happens."
