Milwaukee Bucks General Manager John Hammond announced today that forward Joe Alexander re-aggravated his right hamstring injury during rehabilitation exercises this week.

After consulting with Bucks orthopedic physician Dr. Michael Gordon, M.D., Alexander is expected to be sidelined for a period of 8-to-12 weeks.  Alexander will be re-evaluated on a regular basis and his status will be updated as necessary.

Alexander, 22, originally suffered the injury during voluntary drills prior to the start of training camp on September 17.

In 59 games during his rookie season, Alexander averaged 4.7 points and 1.9 rebounds per game.  In the 2009 NBA Summer League, Alexander tallied 16.6 points, 6.4 rebounds and 1.4 assists over the five game schedule in Las Vegas.
