BJ Penn may have found his new opponent.
A day after news broke that Dennis Siver, Penn's original opponent at UFC 199, withdrew from the fight, the UFC is now targeting a featherweight bout between Penn and Cole Miller, MMA Fighting has learned. The fight isn't official just yet, though. The UFC considered other opponents for Penn over the past 24 hours, however, Miller is the current front-runner.
Miller (21-9, 1 NC) is coming off a no contest against Jim Alers in December after Alers accidentally poked Miller in the eye in the second round of their UFC on FOX 17 fight. Miller's last win was a Jan. 2014 submission against Sam Sicilia. Coincidentally, Miller was on Team Jens Pulver on The Ultimate Fighter season 5 opposite Team BJ Penn in 2007.
The 37-year-old Penn (16-10-2) hasn't fought since his July 2014 loss to Frankie Edgar. Penn retired after the fight, however, he announced his intentions to resume his MMA career earlier this year after joining Team JacksonWink in Albuquerque, N.M.
UFC 199, co-headlined by Luke Rockhold vs. Chris Weidman for the UFC middleweight title and Dominick Cruz vs. Urijah Faber 3 for the bantamweight title, takes place June 4 at The Forum in Inglewood, Calif. Should it materialize, the Penn-Miller tilt is expected to air on the FS1 prelims.
Recipe for a great scrap! 
much more interesting fight
I likely, 2 old school'ers having at it
Cole Miller was getting good for awhile there but that was awhile ago.. I think it's a tough one for BJ
Gannicus - Even better! 
This! The rare switch/upgrade!
Cole has a way longer each, could be destruction.
Is this at 145 or 155? What's the deal with BJ wanting to do 145 anyway?

Upgrade on the matchup IMO.
I don't care where BJ is in his career, he should be on the main card. I recognize the prelims get more views and the last prelim can result in significant PPV buys, but legends belong on the main card.
