During a 31-17 win over the Atlanta Falcons to open the preseason, Allen whiffed on a block to allow a sack.
"The good thing is it's the preseason," Allen said. "You get to go back and learn from the mistakes that you made. That's what the preseason is for."
Vying to be the primary backup to Pro Bowl running back Ray Rice, Allen has only rushed for seven yards on six carries with one reception for 12 yards.
"Anthony Allen is very sharp, very bright," running backs coach Wilbert Montgomery said. "He showed his toughness last year. He's not a very fast guy, but he has the size, he has the strength. I would like to see him run the ball a little bit more."
