What’s far more dangerous than a professional mixed martial arts fight? Weighing in for one. Don’t forget to join us at approximately 4 p.m. ET today for updates, reactions and uncomfortable analysis of dehydrated abdominal walls in the build-up to Saturday’s UFC 101 event from Philadelphia.

4:23 p.m. ET -- B.J. Penn vs. Kenny Florian “For the UFC light heavyweight lightweight championship,” Rogan says. Florian is 155. No shock there. Florian looks like Florian. Penn looks lean at 155 even. Kenny may have the bigger head. If any of this information helps you make a more informed gambling decision, you're welcome.

4:19 p.m. ET -- Anderson Silva vs. Forrest Griffin
Griffin jogs out and disrobes like he’s going for a record. 205. Silva looks happy to be there. Why not? He’s never the guy getting beat up. Solid-looking 205. Pretty electric staredown.

4:16 p.m. ET -- Kendall Grove vs. Ricardo Almeida
Almeida is 185 on the nose, Grove 185.5. Fight of the night material if Almeida has any unleaded in his tank.

4:14 p.m. ET -- Josh Neer vs. Kurt Pellegrino
Pellegrino is 154.5, Neer is 155.5.

4:13 p.m. ET -- Amir Sadollah vs. Johny Hendricks
Hendricks, sporting a beard that’s an easy 7.8 on the Kimbometer, is 171; absentee “TUF” winner Sadollah is a somewhat alarming 166.5. Is 155 in his future?

4:11 p.m. ET -- Shane Nelson vs. Aaron Riley
Riley looks better-conditioned than he has in recent memory. 154. Nelson -- who helpfully has “Nelson” tattooed on his stomach -- is 156.

4:09 p.m. ET -- Tamdan McCrory vs. John Howard
“Doomsday” Howard, sporting the most bizarre flame-styled haircut of all time, is 169.5; McCrory, with very boring hair, dries off with a towel to get every last ounce. 170.

4:07 p.m. ET -- Thales Leites vs. Alessio Sakara
A heavily bearded-and-inked Sakara comes in at 185.5; Leites takes the stage and immediately flops to his back. 185 even.

4:05 p.m. ET -- Matt Riddle vs. Dan Cramer
Cramer steps on the scale, blocking the crowd from ogling new Octagon girl Natasha Wicks. He weighs in at 169.5. Riddle puts on some shades. Still 170.

4:04 p.m. ET -- George Sotiropoulos vs. George Roop
Roop is 154, Sotiropoulos 155.

4:02 p.m. ET -- Jesse Lennox vs. Danillo Villefort
Both welters making their UFC debut. Does that mean the first-time nerves cancel each other out? Villefort clocks in at 170 “and a quarter.” Villefort shakes Dana White’s hand: White is wearing a Phillies jersey. Shameless. Lennox is 171.
