Bishop Montgomery (3-0) took advantage of the depleted Guards, scoring 21 first-quarter points and forcing Bell-Jeff (1-2) to play catch-up the remainder of the game.
The Guards, who lost their second game in a row after beginning the season with an intersectional victory against Monroe, had a difficult time stopping Bishop Montgomery running back Robbie Hou, who rushed for 249 yards in 34 carries and four touchdowns.
Bell-Jeff did its best to stay close with Bishop Montgomery, but the Knights seemed to have a response after each time the Guards cut into their deficit.
The Knights set the tome early, scoring on its first play from scrimmage when wide receiver Bryan Paredes caught a 35-yard touchdown pass from quarterback Louie Soto to make it 7-0 with 10:06 left in the first quarter.
On the ensuing possession, Bishop Montgomery's Jarrett Balter intercepted a pass from Bell-Jeff quarterback Johnathan Porter at the Guards' 35-yard line and returned it to the 7-yard line. Hou then scored two plays later to give the Knights a 14-0 advantage with 8:21 left.
"That put us in a tough spot," said Machuca, whose team will have a bye next week before facing Chadwick in a nonleague contest Sept. 22 at Burroughs' Memorial Field. "We had to stay positive and try to bounce back."
The Guards did.
Mitch Kellogg scored on a three-yard run to trim the deficit to 14-6 with 3:28 remaining in the first quarter. Then, with 33.9 seconds left in the opening quarter, Soto connected with wide receiver Kenneth Ridgeway for a 24-yard touchdown pass to make it 21-6.
Hou then made it 28-6 on an 11-yard run with 5:41 left in the second quarter.
