It is an atypical setup, and something WTVF in Nashville did as well to some extent following the retirement of Hope Hines. Not sure if they still do that type of arrangement.
Also, according to a press release on the LocalMemphis page (http://www.localmemphis.com/content/newstation/story/TV-Stations-Welcome-New-Talent-to-Local-Sports/qg0WzyQ-2USvw_3vH0JKsA.cspx), Doc will have a dual role as both a general assignment and sports reporter for the stations, which is also not unusual as WHBQ did that with Marcus Hunter and Kristin Tallent in the past.
That should be interesting considering the fact that WREG no longer does a sports show on Sundays (they used to have one that was hosted by George Lapides, who does a morning sports show on WHBQ-AM), WMC dropped their show to do an hour-long newscast on Sunday nights, and both stations do abbreviated 10pm newscasts on Friday nights (dedicating the rest of the half hour to an extended sports segment).
