NBA: Cavaliers to lose Irving for three to four weeks

Cleveland Cavaliers guard Kyrie Irving will miss three to four weeks of the NBA season because of a sprained left shoulder, the team announced on Monday.

Irving suffered the injury when he collided with Toronto center Jonas Valanciunas in the third quarter of a 100-96 loss to the Raptors.

An MRI exam on Monday revealed the exact injury, which will require rest and medical treatment and could deny the playmaker's comeback until the final 10 days of the regular season.

Irving has already missed 14 games this season because of various injuries, including 11 missed games in a span of late November and early December due to a broken finger and three games because of a sore right knee.

In 49 games this season, Irving has averaged team highs of 23.0 points and 5.7 assists.

At 21-42, the Cavaliers have the fourth-worst record in the NBA -- ahead only of Washington, Orlando and Charlotte -- and are 12 games behind Milwaukee for the last playoff berth in the Eastern Conference.
