Brooklyn Nets All-Star center DeAndre Jordan is questionable to face the Portland Trail Blazers on Friday.

Jordan sprained his right ankle on Monday versus the New Orleans Pelicans. He was limited at Thursday's practice:

If Jordan doesn't play against the Blazers, Jarrett Allen will start.

In his first season with the Nets, Jordan is averaging 6.1 points, 9.3 rebounds, 1.6 assists and 1.3 blocks per contest. He's shooting 56.3 percent from the field.

The Nets are 3-4 on the young season. They are coming off a home win over the Pelicans. Brooklyn is putting up 121.0 points per game, which is good for second in the NBA. However, the Nets are struggling on defense, as they are giving up 120.3 points a night, 27th in the league.

Jordan signed a four-year, $40 million deal with the Nets this offseason in free agency. He split time last season with the Dallas Mavericks and New York Knicks. Jordan has started three games this season and come off the bench four times.

Brooklyn, of course, is led by All-Star point guard Kyrie Irving, who is averaging 31.7 points per game. Since two-time Finals MVP Kevin Durant is going to miss the entire season, the Nets will ultimately go as far as Irving can take them.
