Mavericks vs. Cavs: Game time, TV schedule, preview and more

On Nov. 5, the Cleveland Cavaliers notched an impressive 108-101 road victory over the Los Angeles Clippers to move to 2-2. Since that point, they've lost four games in a row, and enter Saturday night's matchup with the Dallas Mavericks looking to rediscover the formula that helped them to those two early season wins.

First order of business for the Cavs is fixing their defense, which ranks last in both points allowed and defensive efficiency. The only game this season in which the Cavs gave up less than 100 points was in their first game of the season, a win over the Washington Wizards. Unfortunately for Cleveland, the Mavs have been one of the most potent offenses in the NBA this year, ranking fourth in offensive efficiency.

The Cavs will potentially get a boost from the return of Tyler Zeller, who suffered a concussion and a fracture cheekbone in that loss to the Clippers. Zeller will come back to the court wearing a protective mask, and will look to bolster the team's frontline behind Anderson Varejao and Tristan Thompson.

Saturday night's game tips off at 7:30 p.m. ET on Fox Sports Ohio.
