Follow along here, as we'll trace this chronologically:
• Victor Cruz emerged as a star receiver last year, and likes to do a salsa dance after he scores a touchdown.
• In Week 10 last season, 49ers cornerback Carlos Rogers did a salsa dance after picking off an Eli Manning pass during San Francisco's win over the Giants.
• This bothered Cruz, who wrote about the incident in his book, Out of the Blue. (Yes, he wrote a book after one season of regular NFL action.) Here's Cruz, from his book, via the Sacramento Bee:
"Then with his teammates cheering him on, he did a sarcastic salsa dance over me," Cruz wrote. "The Candlestick Park crowd went ballistic, but I wasn't laughing. It was a sign of disrespect. Instead of getting up and retaliating, though, I sat and watched Rogers finish his cheap Victor Cruzimitation. I promised to never forget it. I wasn't sure when the opportunity would present itself but I was confident I'd get payback for that dance."
(When the two teams met in the NFC title game last year, Cruz had 142 receiving yards, but no opportunities for an end-zone dance.)
• Fast forward to this week, as the Giants and Niners prepare to meet at Candlestick Park: Rogers says he actually likes Cruz's dance, but that won't necessarily stop him from mimicking it again. Via the Sacramento Bee: "I really can't do it as good as him. But if I make a play or get an interception on him in my mind, just do his dance."
• Cruz responded by skipping practice this week and taking extra salsa lessons to ensure he's the superior dancer on Sunday, should both players make an impact play.
Okay, we made up the last one. The rest of this is all very real, though.
