Starting running back LeGarrette Blount fumbled on Tampa Bay's first play from scrimmage, leading to Olindo Mare's field goal.
Blount was benched until the second half.
"It's a basic thing, and to fumble like that, that's unacceptable," Morris said. "If some players aren't ready to play, we'll put others in."
Blount has been in trouble for fumbling before and lost carries to Caddy Williams last year at key times in the game when he just wasn't trusted. This year, with Earnest Graham lost for the year, the Bucs didn't have many options but it didn't stop the team from sitting Blount this time.
