TAMPA — One of the best athletes in Tampa Bay, Jefferson junior Tyrese Spain, may not be available Friday night for one of the biggest local games of the year, Jefferson vs. Jesuit in Class 5A, District 10.Jefferson coach Jeremy Earle said in a text message Thursday night that Spain's availability remained "a game-time decision" and that Spain has "a pretty good limp."The problem is a tender knee, which Spain twisted last Friday on the first play of the Dragons' 27-19 victory over Sickles. After Spain went down, he was sent straight to the hospital for X-rays.On Wednesday, Earle said that Spain's doctors "were encouraged because the swelling had gone way down."Spain, a Division I-A recruit who plays full-time at defensive back, receiver and/or running back and as a kick returner, accounted for more than 2,000 all-purpose yards last year. In 2015, Spain played mostly at quarterback, filling in for starter Cade Weldon who tore his ACL during the first game of last season and didn't return for the rest of the year.For both Jefferson (1-1) and Jesuit (2-0), Friday's game is the first in district play, but it is widely considered a matchup between the district favorites.If Spain is unable to play, look for sophomore running back Niko Duffey to get more than his share of touches. After Spain went down last week against Sickles, Duffey had 19 carries for 157 yards and a touchdown, and two receptions for 25 yards.
