Backup quarterback Shawn Robinson was already on his way to playing more for TCU, looking for an offensive spark, in the final two games of the regular season. Now it may be even more than the Horned Frogs planned. Starting quarterback Kenny Hill is among four starters described as “between probable and questionable” by coach Gary Patterson for the 11th-ranked Frogs’ game at Texas Tech on Saturday. The list includes linebackers Travin Howard, the team’s leading tackler, and Montrel Wilson and strong safety Niko Small. Already, leading rusher Darius Anderson is out for the season, and placekicker Jonathan Song was unable to kick last week against Oklahoma. Center Patrick Morris, who has missed six games, will be available, although only for limited duty. “We’ve lost guys before,” Patterson said. “Bottom line to it is, we have enough players to go win a ballgame.” Patterson declined to specify any of the players’ injuries, or if they are injured. Hill and Howard spoke with reporters after the 38-14 loss at Oklahoma. Typically, TCU does not bring injured players to the interview room. “Everybody else has been affected by injuries,” Patterson said. “There’s guys that have been saying, ‘I need to be playing more.’ Well, here’s your opportunity, if those guys can’t go.” Patterson said Hill, Howard, Wilson and Small could all be game-time decisions, however. “If I thought they were out, I would just tell you they’re out,” Patterson said.
