The restructured lineup at 1500-AM, set in motion last week when morning show co-host Jeff Dubay was let go, will prove to be a significant shakeup at the sports talk station, according to a source.

Phil Mackey, who had been on from 4-7 p.m. -- the first two hours with Star Tribune columnist Patrick Reusse -- will move into the 9 a.m. to 1 p.m. slot as the co-host with Judd Zulgad.

Reusse will remain in the 4-6 p.m. drive time slot as a solo host.

The changes will become effective starting Feb. 3, the Monday after the Super Bowl.

In announcing the decision on Dubay last week, the station said it "is not a reflection of Jeff's performance. It is a reflection of our current operating environment."
