The Chicago Bulls will likely be without a couple of their key players for their game against the Milwaukee Bucks on Monday night, as guard Kris Dunn and forward Otto Porter Jr. are both listed as doubtful, according to Bulls reporter Kelly Crull.

Dunn is dealing with migraines while Porter is nursing a leg injury.

On the season, Dunn has played in 33 games and is averaging 11.4 points, 6.3 assists, 4.1 rebounds, and 1.4 steals over 31 minutes per game while shooting 43.2 percent from the floor, 31.7 percent from three-point range, and 78.4 percent from the free-throw line.

Known for his defense, the 24-year-old is in his second season with the Bulls after coming over in a trade that sent Jimmy Butler to the Minnesota Timberwolves during the summer of 2017.

During his first year in Chicago, Dunn appeared in 52 contests and registered 13.4 points, six assists, 4.3 boards, and two steals across 29.3 minutes a night while making 42.9 percent of his field-goal attempts, 32.1 percent of his long-distance tries, and 73.7 percent of his foul shots.

He played his collegiate basketball at Providence and was originally selected by the Timberwolves with the fifth overall pick of the 2016 NBA Draft.

Porter just arrived in the Windy City earlier in the month after coming over in a trade with the Washington Wizards.

Through six games with the Bulls thus far, Porter is averaging 17.8 points, 5.2 rebounds, and 2.7 assists over 31.8 minutes per game, connecting on 54.5 percent of his shots, 51.9 percent of his triples, and 81.8 percent of his free throws.

Overall this season, the 25-year-old Georgetown product is recording 13.3 points, 5.6 boards, two dimes, and 1.4 steals a night.
