Corey Walden was an undrafted rookie that played on the Celtics summer league team. According to reports, he'll get a training camp contract that has a small guarantee but will likely end up with him getting waived and signed to the Maine Red Claws.
As @EricPincus notes. Corey Walden to BOS, 25k guaranteed. Will be assigned to Maine if he doesn't make the roster. Expect more of these.— Bobby Marks (@BobbyMarks42) August 4, 2015

Walden, 22, was hobbled by a hamstring injury while with the Celtics summer league team, but averaged 18.8 points, 4.0 rebounds and 3.8 assists as a senior at Eastern Kentucky. The Celtics have also reportedly added Alabama wing Levi Randolph for training camp.
One guy that was offered a contract but won't be with the Celtics in training camp is former lottery pick Joe Alexander.

The 6-foot-8 forward has not appeared in an NBA game since 2010, when he played eight games for the Chicago Bulls. Since then, the former No. 8 overall pick has bounced around the D-League and overseas.
Training camp is still several weeks away and the bulk of the offseason is behind us, but the Celtics are still looking under every rock to try to find gold.
