TAMPA, Fla. -- Bill Belichick says the New England Patriots still have work to do to get ready for the regular season. It's not clear whether that includes more playing time for Tom Brady.

Brady threw an interception that was returned for a touchdown and was sacked twice in his most extensive action of the preseason during a 30-28 loss to the Tampa Bay Buccaneers on Friday night.

"We obviously got off to a slow start but played a little bit better in the second half," Brady said. "But we really need to string it together for four quarters in order to beat good teams on the road."

Belichick said, "We'll worry about next week, next week," when asked about how much he expects Brady to play in Wednesday's exhibition finale against the New York Giants.

Brady wasn't saying whether he'd lobby for more playing time.

"Whatever Coach decides. ... He's the one that makes all the decisions, so we'll just listen to what he has to say," Brady said. "And if he says play, we're going to play."

First-round draft picks Mark Barron and Doug Martin scored touchdowns for Tampa Bay.

Barron intercepted a pass tipped by Ronde Barber and returned it 22 yards for a first-quarter TD. Martin scored on a 1-yard run that finished a game-opening drive led by Bucs quarterback Josh Freeman.

Brady played three quarters in his most extensive action of the preseason but didn't really get the Patriots' offense on track until after Tampa Bay had built a 23-7 lead. He finished on a high note, though, throwing a 16-yard touchdown pass to Rob Gronkowski on his final play.

"I think it was pretty obvious that we've got a lot of work to do. We've got a long way to go. We didn't perform, I think, to what the level we need to at any area," Belichick said. "When you can't score offensively and give up a lot of points on defense, nobody can make any plays in the kicking game, then you don't have a real good chance to win. And that's pretty much the way it was tonight."

Freeman played into the third quarter, finishing 10-of-19 for 102 yards, no touchdowns and no interceptions. Connor Barth kicked a 56-yard field goal, and Kai Forbath added field goals of 51 and 55 yards before Freeman's backup, Dan Orlovsky, tossed an 8-yard scoring pass to Sammie Stroughter in the fourth quarter.

Bucs guard Davin Joseph was carted off the field in the first half with what appeared to be a right knee injury. There was no immediate announcement on his status.

"It doesn't look good, but we'll get an evaluation (Saturday)," said coach Greg Schiano, who didn't discuss specifics about the two-time Pro Bowl selection's injury.

"That's unfortunate," Freeman added. "Davin is one of our leaders."

The Patriots traveled to Florida early in the week to practice with the Bucs twice in preparation for the game -- workouts Schiano felt would be especially beneficial to his players because of what they could learn from being on the field with Brady and other veterans who have been vital to New England's success.

Freeman completed passes of 25, 14 and 10 yards to Vincent Jackson on an eight-play, 68-yard drive that Martin finished with a 1-yard TD run. Barron's interception return -- one play after Michael Bennett sacked Brady for an 8-yard loss to the New England 7 -- made it 14-0 late in the opening quarter.

Brady threw seven passes in New England's preseason opener against New Orleans, then sat out the Patriots' second exhibition against Philadelphia. In what likely will be the most playing time he'll get before the regular season, the two-time Super Bowl MVP completed 13 of 20 passes for 127 yards, one touchdown and one interception.

The Bucs, last in the league in sacks with 23 last season, dropped Brady twice and pressured him into bad throws on at least three other occasions.

"I thought the guys got after the quarterback pretty well," Schiano said. "As always, that ties together, coverage and pressure."

Brady directed one scoring drive in the opening half, completing three of four passes for 29 yards on a 12-play, 81-yard march extended by a pass interference penalty on Barber and featuring a 29-yard run by Stevan Ridley. Ridley finished the drive with a 1-yard run, then also played a prominent role in the final possession led by Brady.

Freeman, meanwhile, cooled after hitting five of his first six passes. The Bucs settled for Barth's long field goal after the Patriots turned the ball over on downs at their own 41, and Forbath added his 51-yarder as time expired to hike Tampa Bay's lead to 20-7 at the half.

Barron was the seventh pick in this year's draft, and the former Alabama safety is being counted on to bolster a defense that ranked among the worst in the league in 2011, when the Bucs yielded a franchise-record 494 points. Martin was the 31st pick overall and is bidding to become the starting running back.

"Mark played faster this week. He looked more confident in what he was doing," Schiano said. "That's what rookies do. They learn and they get better."

Ryan Mallett followed Brady in the fourth quarter for New England and threw a pair of fourth-quarter touchdown passes -- 8 yards to Jeremy Ebert and 3 yards to Jesse Holley -- to make it close in the final five minutes.
