The story about Brock's contract noticeably does not mention any length of the contract. (That was specifically mentioned when they revealed he'd be back last time this happened.) A short term deal to get him thru the Saudi Arabia deal still allows him plenty of time to go back to UFC.
Nous ne nous pouvons pas sortir. BROCK~! hasn't un-retired and reentered the USADA testing pool so he's 10 months or so away from being creamed by an elite heavyweight or steamrolling a kickboxer with no wrestling.
So him staying a bit longer isn't a huge surprise.
Cageside (cagesideseats.com) is running a rumor that Lesnar's contract was extended so he could drop the title to Reigns in front of a "more favorable" crowd. My guess is that they think Jeddah will be that favorable crowd. And they're probably right too.

And mine are long and sharp, my lord, as long and sharp as yours!
I seem to recall they had a commercial for this on either Raw or last weeks Smackdown (haven't seen this week yet) It's one of those "if you have been in an accident, got hurt, etc etc you might be entitled to money" commercials.
