HOUSTON --There's criticism off the field for Texans cornerback Kareem Jackson. It has to do with pictures he posted on Twitter, showing cockfighting during his trip to the Dominican Republic. We reached out to Jackson through his agent but they were not talking on Tuesday; however we do have the pictures he tweeted over the weekend from the Dominican Republic while on vacation. In his rookie season with the Texans last year, Jackson made a few mistakes. And now some are saying the 22-year-old rookie made another one off the field. "What an idiot, that you know, he wouldn't learn from the Michael Vick issue," football fan Joneau Shelton said. Using his Twitter account, No. 25 documented his vacation to the Dominican Republic and seat at a cockfighting event. He posted pictures of some of the birds and elaborated on the experience, tweeting: "My first time ever seeing chicken fight till the death it was crazy ..." and "look at all these people that be at these chicken fights, you would think it was a college football game." Though cockfighting is legal in the Dominican Republic, Texans fans say better judgment was needed. "It's legal, sure... stupid, yes," football fan Jay Lowe said. Texans fans we talked to at Christians Tailgate Sports Bar in the Heights say an NFL player must learn how to handle the spotlight. "Just because it's legal to do something, that you know in your heart is wrong, don't make it right because you're in a certain place. It's about morals," Lowe said. The Houston SPCA says a Texans player advertising his attendance at a cockfight doesn't help local efforts to stem the events, which are illegal in Texas and the U.S. Just last year, they investigated more than 15,000 cases last year of animal abuse, cruelty and neglect and rescued countless chickens and confiscated the razors tied to their legs in the matches. "They frequently are suffering from mortal injuries, when they are rescued from these fights; they literally strap knives onto their legs and they fight them to the death," said Stacy Fox with the Houston SPCA. We also contacted the Texans on Tuesday; they tell us they are making no official comment publicly, saying they will handle this internally.
