There is no time frame for Kubiak's return.
The son of Bum Phillips has nine seaons of head-coaching experience, with the Denver Broncos (1993-1994), Buffalo Bills (1998-2000) and Dallas Cowboys (2007-2010). He also was interim coach twice with the New Orleans Saints in 1985 and Atlanta Falcons in 2003. Phillips has logged a combined record of 82-61.
Phillips, known as a player's coach, has plenty of experience running clubs and probably shouldn't have any issues handling the head-coaching responsibilities.
