Stop me if you've heard this one before.

Former UFC welterweight number one contender Thiago Alves had trouble making weight today (Nov. 4, 2011) for his UFC 138 fight against Swedish newcomer Papy Abedi.

"The Pitbull" weighed in at 172-pounds, one pound over the limit of 171 for their main card welterweight scrap set for the Spike TV airwaves from the LG Arena in Birmingham, England.

Alves had two hours to make his mark and eventually shed the excess weight.

It will be interesting to see what repercussions await the Brazilian in the wake of his latest scale snafu. When he failed to make weight at UFC 117 against Jon Fitch, promotion president Dana White insisted that would be his last fight at welterweight.

Alves eventually convinced White to give him one more try, which delayed a trip north of his division, but after today it could be 185 or bust.

And with a loss to Abedi, it could even spell the end of his UFC career.

Stay tuned.
