Grizzlies point guard Mike Conley has been diagnosed with left Achilles tendinitis and will miss the next 3-4 weeks.

Conley has already sat out nine games so far this season, and this diagnosis will force the ironman PG to miss the most games since his rookie year.

The Grizzlies already lost Mario Chalmers for the season and are currently starting D-League callup Briante Weber at point guard.

From the Grizz:

Conley has missed the last two games with left foot soreness and received an additional examination yesterday, which showed Achilles tendonitis. He will remain out and will be re-evaluated in 3 to 4 weeks.
