An oversight caught by a Denton Guyer school counselor might have kept the Wildcats from potential problems.Guyer on Monday forfeited its Sept. 5 win (35-14) over Colleyville Heritage after it was discovered last Thursday that a foreign exchange student on the Wildcats’ roster was ineligible.The player, a kickoff specialist, played for Guyer last year and had already attended high school for three years before 2012.UIL rules (Constitution and Contest Rules: General, Section 465) allow an exchange student to participate if the student “has not completed four years of high school attendance.” Denton ISD athletic director Ken Purcell said it’s uncommon for exchange students to spend more than one year at a school.“It kind of fell through the cracks,” Purcell said. “This is my 41st year [involved in high school athletics], and I’ve never had this happen before.”Last week, a counselor at the school was preparing transcript information for college recruiters and noticed the student had spent three years at another high school before attending Guyer, Purcell said.Because of the number of credits the exchange student had coming in, he was enrolled as junior in 2012, meaning this year is his fifth in high school.The issue was reported to Guyer coach John Walsh, and the player didn’t participate in Guyer’s 35-17 win last Friday over Flower Mound Marcus, Purcell said. The Wildcats are 1-2.They lost their season opener to state-ranked Cedar Hill. Guyer started last year 1-2 before going on to win the Class 4A Division I state championship.“The information you heard was true,” joked Heritage coach Mike Fuller, whose team is now 2-1. “It still doesn’t change the fact they whipped us.”Keller’s quick startCarl Stralow just needed some time.Keller’s second-year head coach has gotten that, and things seems to be clicking for the Indians, who improved to 3-0 with last week’s 20-0 win over Hurst L.D. Bell.“Any time you have more time around kids, you know what they’re more capable of doing,” Stralow said. “A year helps that. We are different in play-calling and offense and defense to match this particular group of kids.”With Friday’s victory, Keller matched its 2012 win total. The Indians were opportunistic in getting there. Bell outgained Keller 355-193 in total yardage, but Keller forced five fumbles and recovered three. “We’re not getting any style points,” Stralow said. “We’re just about ready to print shirts that say ‘Win ugly, win often.’ ”Stralow said his team still needs to “clean up” each segment of its game. The Indians will get a chance to do that during this week’s bye. Dunbar rollingConfidence is high at Fort Worth Dunbar, where the Wildcats are 3-0 after beating Saginaw Chisholm Trail 54-7 on Friday. “It’s going in the right direction,” Dunbar coach Todd Lawson said. “We feel we’ll be hard to beat, because we have a number of weapons we can use.”Running back Taylor Martin led the way Friday, rushing for 302 yards and five touchdowns. Quarterback La’Quarrian Peoples threw two touchdown passes, one to Ty Watson and one to DeVonta Kinney. The Wildcats’ quick start is a contrast to last season, when they began 1-2. Dunbar finished the year 5-6. “We’ve just been talking with the kids as far as staying focused and being focused through four quarters,” Lawson said. “The kids are feeling real well and feel good about this weekend.”Boswell riding winSaginaw Boswell’s 14-9 defeat of Birdville last week snapped a 13-game regular-season win streak by the Hawks.The Pioneers (1-2, 1-0 District 6-4A) got a big performance from a running back of their own. Antoine Stevenson ran for 130 yards and a touchdown that put Boswell up 14-3 in the fourth quarter.“Antoine played the best game of his career,” coach John Abendschan said. “He made plays after contact. Many times, he made first downs after getting hit short of a first down. He’d get hit a pretty good five yards short, and he found a way to get over the line.”Voting continuesBe sure to check out the fan vote for Player of the Week at dfwVarsity.com.
