Shiner had a bye week on Friday and defeated Kenedy, 39-18, in its district opener on Oct. 11. The Comanches play at Three Rivers this week and is a similar team to the Comanches.
"This will be just the second time we have played them," Shiner head coach Steven Cerny said. "They are physical and content with picking up three or four yards a play to control the clock."
Three Rivers is a running team like Shiner but runs a Wing-T style offense.
Leading rushers are Robert Moreno (49-435, three touchdowns) and Paul Almendarez (59-386, six touchdowns).
Quarterback Hagan Johnston has completed just 7-of-16 passes for 141 yards, two touchdowns and two interceptions.
"We have to play assignment football on defense and not chase ghosts," Cerny said. "We have to fill the gaps quickly."
Three Rivers' key defensive players are linebacker Weston Huff, linebacker Adam Romero and defensive back Dillon Guajardo.
"With two teams that both run the ball a lot, this game probably will go quickly," Cerny said. "It is important we take advantage of our offensive possessions. We also cannot turn the ball over."
