Answer based on context:

The first regular season game for head coach Raheem Morris saw the Buccaneers fall to the Dallas Cowboys by a score of 34-21. Running back Cadillac Williams returned as a starter, and rushed for 97 yards and one touchdown. Quarterback Byron Leftwich threw for 276 yards, one touchdown, and no interceptions. The Buccaneer defense, however, gave up three big plays in the loss. Dallas quarterback Tony Romo threw for a career-best 353 yards. Three long touchdown passes (66, 80, 44 yards respectively) put the game out of reach. Early in the fourth quarter, Tampa Bay closed the deficit to 20-14, but Romo's 80-yard catch & run to Patrick Crayton put the Cowboys ahead for good. On specials teams, kicker Mike Nugent had one field goal attempt blocked, and shanked another.

how many yards did Leftwich throw? \
