The Brooklyn Nets announced Monday that point guard Jeremy Lin is expected to miss three to five weeks after re-aggravating a left hamstring strain as the team continues to struggle at the bottom of the Eastern Conference.

Lin, who has appeared in only 12 games since signing with Brooklyn as a free agent last summer, has missed the Nets last 10 games because of the injury. The Nets have lost 10 straight, and most recently fell to Charlotte 112-105 Sunday.

Brooklyn continues to have the worst record in the East and the entire NBA, sitting five games back of 14-20 Miami and seven wins behind the Western Conference’s worst squad and one of Lin’s old team, the Los Angeles Lakers. The 28-year-old hasn’t appeared in a game since Dec. 26.

Lin exacerbated in the injury during rehabilitation, Nets general manager Sean Marks said in a statement.

When healthy this season, Lin has been effective for Brooklyn. He’s averaged 13.9 most – the most since his wild 35-game run with the New York Knicks dubbed “Linsanity” – to go along with 5.8 assists, 3.3 rebounds and 1.3 steals per contest.

Despite missing most of the first half of the season, Lin earned adoration from fans around the world in the NBA’s All-Star Game voting. He finished eighth among East guards with 202,502 votes, more than former Hornets teammate Kemba Walker and Boston Celtics guard Avery Bradley.

Lin was supposed to lead Brooklyn during its most recent rebuild, but his absence has forced first-year head coach Kenny Atkinson to look to his bench. Third-year guards Sean Kilpatrick and Bojan Bogdanovic have mostly stepped up with 14.2 points apiece per game, though rookie Isaiah Whitehead leads the team with 2.8 assists a contest.
